Each calf dome is 5' tall, about 7' in diameter. We use them as portable shelters for pasture farrowing, covers for sacks of feed, confining laying turkeys and (gasp) even their intended purpose of bottle feeding calves.
put a 30 gallon garbage can with some hay in it as a nesting box (turkey hens are big animals, and a 30 gallon can is about the right size), and string this recycled construction fence across the entrance. You don't need much of a barrier to keep turkeys in. The orange fencing is mostly a visual barrier.
The orange fencing is also known as pig dental floss. They love it. So yesterday three of the smallest pigs I've got slipped out of their electric fence, and over to the turkey domes, and proceeded to let every single turkey loose. They pulled the orange fencing off the front and out came the turkeys.
This was such a success in the eyes of the pigs that they decided a roadtrip was in order. So these same small pig terrorists chewed the power cord off the electric fence, and then proceeded to lead the entire herd out of the pasture and onto the road. And then down the road. And then over the bridge. All in all, about a mile down the road.
So when I got to the farm, I was stopped at my gate by a neighbor who'd seen the pigs down the road, and the dogs and I herded them back over to the property, only to discover when I got there that all 70 turkeys were out. So I spent 4 hours chasing and netting turkeys, fixing the fence, netting more turkeys, herding pigs back in, and so on.
Moral of this story: Good fences, particularly perimeter fencing, is worth its weight in gold. Guess what my next project will be.
