So, I went to a meeting with our Urban Gardening group from church, and we went to one of the peoples houses to see their set-up. I have a question about it. They built really nice enclosures. One side was the back side of a 6' wooden fence. They then completely enclosed it and didn't have a coop, but they did have a doghouse. Is that advisable? We have really mild winters, and very rarely will it snow. They build the enclosures with 2x4s and on the oustside they put fencing, and on the inside (and on the other side of the 2x4) they put the 1/2" wire mesh about half way up, creating a 4" gap between the inner and outer fence, so no chance of racoons or possum getting in. The also said that if the birds catch certain diseases that you have to burn a wooden coop? Is that true?
