My goats have been living in an 800 sq ft pen and sleeping in a 10 sq ft box. I know.That's pathetic. But, they were small. They liked the coziness of the close quarters. However, this weekend my father and I built them a more proper shelter.
It's a three sided shed with a sloping roof.
1-relatively skilled handy-person/capenter
3-sheets of 3/4" plywood (4x8)
4-right angle braces
2 million screws
