I tried to add a picture on here, but am having some trouble with that. Anyhow, I improvised a nest box for my chickens (don't laugh) out of a cat litter bucket. I have bantams, and they barely fit, but they have been using it regularly, and even now that I have "real" nest boxes in there, they prefer the bucket. I used a bright yellow kinda rectangular shaped bucket. All I did was cut the flap part of the lid off, screwed a 2x4 to the little bit of lid that was left (I had to add a strip of 1/4 inch plywood under it so it would sit more solidly) and added shredded newpaper. They have been using ever since. If someone can tell me how to add the picture I'd be happy so send it on here as well. I was going to use it as a feed bucket, but it worked as a nest, and I had to share this idea with Ya'll.
