Spring Cleaning

There’s nothing goats love more than a clean house…Well maybe some dry oak leaves.  Yesterday Carla and I took advantage of the wet weather to do a much needed hose-out of the trailer and lay down fresh wood shavings.  A couple of these pillows would make it nice and cozy too.

Next time I’ll try to remember to take a before picture.  Yowsa.

Soggy Goats

The goats don’t seem to be enjoying the downpours we’ve been having at the yard lately, but we do what we can to keep them dry!

Support the SF Urban Agriculture Alliance Zoning Proposal

Date: Thur, February 17, 2011
Time: 1:30 PM
Location: City Hall, San Francisco

Little City GardensThanks to the hard work of many people, last month the City officially announced a proposal that, if passed, will update San Francisco’s zoning regulations to explicitly permit gardening in all areas of the city and also officially allow for the sale of produce grown in these gardens. Whoo-hoo!

Please, if you can, join the San Francisco Urban Agriculture Alliance at the public hearing to voice your comments and show your support.

The more people who are present at City Hall for the review of this proposal, the more apparent it is to the Planning Commission that residents of San Francisco value agriculture as a vital part of our city.

We feel strongly that in order for agriculture to be a lasting fixture in our city, made up of a diverse mix of people, skills and backgrounds, there has to be a way for urban farmers to make a living.

Here is an article about the proposal that appeared on the front page of the Chronicle last month and another article in the SF Examiner.

If you don’t have time to come to the February 17th Planning Commission hearing you can still support the passage of this important legislation by signing this petition.

King of the Mountain and High Hoops



These warm days are great for taking the goats out. Today they played King of the Mountain on some rubble. We saw a shiny emerald hummingbird in the fennel stalks and two red-tailed hawks circling the concrete piles and lights. Poppies are popping and the sourgrass flowers add some color to the goats forage as well.

HORRAY FOR BARN RAISING …. AND WELDING! The guys who work at the Railroad have made a lot of progress in the last few weeks getting the new site of the goat pen ready. Designed by ReBar, the structure is combines a shipping container and a high hoop-house top to centralize the herd’s shelter, hay storage, and other official goat herding business. We dream of electricity in our ‘barn,’ cozy stalls for the goats, and maybe even a surface to put down our coffees that’s not covered in hay. Just west of the site is the long stretch of land for browsing, so once we make the move, the goats won’t have to scurry around the maze of rail cars, tracks, and lumber piles when we take them out. Also, a friend is keeping bees out that-a-way.

Goat Fencing 101

About half or more of our clients don’t have fencing around their properties, which makes goat grazing an interesting challenge. I get asked about it all the time, so I thought I’d just share how we deal with these goat containment conundrums with you all.

Surveying the Site

Our first step with every potential client always is to visit the property and do a site inspection to answer these questions: Will goat grazing be able to accomplish what the property owner wants? Is it practical? Is it safe?

We don’t accept every client who wants to hire us. Every so often we will turn a job down because the answer to one or all of those questions is “no.” Outside of toxic plants and predators, my main safety concern is whether or not I can successfully keep the goats where I want them to be. Them escaping is my nightmare (and yes, I’ve actually had nightmares about this).

The best solution we have is to install a temporary electric fence. This isn’t super complicated, but every so often there are circumstances that prevent us from using this. For instance, some yards are so overgrown that the ground is buried 4 feet under a mess of thorny blackberry, keeping us from getting the fence spikes in the ground. Ground that is too dry or sandy can also be problematic, for reasons I’ll discuss below.

Assuming the site is a good candidate, we’ll move forward installing the electric fence the day before the goats arrive (it can take hours, and we’d rather not have the goats bored in the trailer the whole time).

Our Equipment

For the purposes of this blog, I’m only going to address the type of fence that we use. Just be aware that there are other types out there. We get all of our fencing from Premier 1 Supplies. After a lot of research, experience, and discussions with other ranchers, I’ve found this company to have the best quality equipment, and the most friendly, helpful staff. The type of fence we use is the E’Stop 9/42/6 electric netting. The numbers mean that the fence has 9 horizontal twines, is 42″ tall, and has vertical twines every 6 inches. We use 164′ rolls with the double spike, which I’ve found makes the fence easier to install and less saggy. We use a Stafix x3 battery energizer (we also have a Speedrite Delta 3B which I’m having problems with right now), deep cycle marine batteries, and copper ground rods.

Energizer

Stafix energizer sends the electric pulse through the net.

How does it work?

If all goes well, our fence will deliver about a 7,000 volt shock to anything that touches it, keeping the goats in and everything else out. The shock is sent out in a pulse – the actual amount of time the fence is “hot” is about 3/10,000ths of a second, and this happens every 1.5 seconds on the “fast” setting that we keep it on. It can go as slow as every 2.5 seconds, which isn’t fast enough for curious goats in my opinion.

Have some basic understanding of how electricity works goes a long way when it comes to using these fences. Farming is just one of those jobs that requires you know a little bit about a lot. So here’s a brief rundown, and hopefully I won’t confuse you too much.

For electricity to do what you want it to, it needs to complete a circuit. The energizer generates a high voltage pulse (powered by the deep cycle battery), sends it to the fence, and when an animal touches it, the electricity takes that opportunity to complete the circuit and head home, back to the energizer. The electricity goes through the muscles of the animal (causing the pain), into the earth, and travels through the moisture in the earth to the ground rods that lead back to the energizer.

This brings me back to the comment I made earlier about dry soils being less than ideal for electric fencing. When we install the fence, we put about 9′ of ground rod into the soil. The rods are connected to the energizer, connecting it to the moisture in the soil. Dry or sandy soil is a poor conductor of electricity, and can render your fence practically useless.

I also make a point of walking the fence daily to check for shorts (vegetation, especially when wet, sucks energy from the fence if touching the hot wires) and sagging or fallen posts.

Why Such High Voltage?

We have a fence tester that lights up, indicating the voltage of the fence up to 7,000 volts, which is where I want it for me to feel confident in my fence. I’ve accidentally brushed up against it on more than one occasion, and it’s a serious shock. But take a look at a goat, and you’ll see that they’re quite well insulated. Fur and hooves don’t conduct electricity well, so it takes a relatively high voltage for them to feel it.

The shock is very uncomfortable for the 3/10,000ths of a second that it lasts, but doesn’t cause any lasting damage and is perfectly safe for people and animals.

Last but not least, goats have to be trained!

Goats in Fence

Trained goats respect the fence even when food is right on the other side.

An electric fence is a psychological barrier, not a physical one. This is very important for anyone who wants to use electric fencing to understand. You have to train goats to respect it, and once they’re properly trained, they should never even think about touching it again. My method is this:

Make a small paddock with the temporary fence – just big enough to hold the goats comfortably with room to mill around. I build this out from the entrance to their pen so they can go in and out of the training area as needed. This gives them an escape route in case they get really freaked out and make a run for it. Make absolutely sure that your system is well grounded and outputting at least 7,000 volts. Never train animals to a weak fence, and whatever you do, don’t let them touch the fence when the system is off!

Being calm is key here. With the fence on, herd them into the fenced area and let them check it out. You don’t need to push them toward the fence – they’re curious animals, and they’ll figure it out on their own, so stand back and observe. Don’t leave them alone with the electric fence while you’re training them. You never know how they’ll react to the shock – hopefully they’ll back up, but sometimes they get confused and charge through it, so be ready for anything.

Training doesn’t take more than a day of this in my experience, but I usually do a second day where I repeat the process but put a bale of hay just on the other side of the fence. If they keep their distance from the fence despite seeing that tasty hay, you’ve got trained goats.

Despite all of the best efforts, there’s a chance a goat may become a fence jumper. If your goat is tall enough that he can see clear over the fence just standing next to it, chances are he’ll think it’s a big joke and hop right over, so make sure you get a fence height that’s right for your herd. Remember that electricity needs to complete the circuit for them to get shocked, and airborne goats don’t do this. They need to have their hooves on the ground to be shocked. Fence jumping goats shouldn’t be tolerated – goats are fast learners, and they’ll have your whole herd trained to see the fence as a fun obstacle course in no time. Once a goat has had a few successful escapes, there’s not much hope for retraining him. Those goats can be sold, eaten, given away, put elsewhere on the farm, anywhere but with your trained goats when they’re in an electric fence.

Even trained goats shouldn’t be left in an electric fence when the electricity’s off. All it takes is one of them accidentally bumping into it and realizing that it’s safe to touch. You can’t underestimate how smart goats are.

Goats can always get through an electric fence if they really want to. If they feel like they’re in danger or if they’re not getting proper nutrition and can see food on the other side, they’ll get over no matter what. They will just decide it’s worth getting shocked to get out, so fenced animals should always be well cared for, comfortable and safe.

One final word of advice: when you’re not using your electric fence and energizer, store them somewhere rodents can’t find them. They just love eating electric wires!

Feasting and Farewells

Carla in the trailer

THE GOATS had a job up in twin peaks last week, which meant they got to clear lots of brambly bushes, pompous grass, and wild radishes.

the only snafu was getting the truck stuck in the mud at the railyard on the morning we were dropping them off.  to get it out, we tried unhitching the trailer, layering the ground with wood chips and boards, pressing the gas and pushing. however, the wheels spun out, 6 inches deep by then into ground soft from rains, so we got another truck to pull us out.

Kacie at Twin Peaks job

this was our last job with the 9 original Boers. the wethers were sold to a farm south of sf. the 50 remaining goats are much more trustworthy when it comes to respecting electric fences. younger and smaller, they are bulking up with winter coats.

herding

We let the goats roam around the other day. You can see the bay and Mt. Diablo beyond the waddles and horns. The herd was pretty happy to munch on fresh wild radish & little grasses and was curious about foxtails too. Suddenly, a old bearded lady goat led the herd back to the pen, making our job of rounding up the stragglers quick easy.
