We did PLAN to make the chicken tractor first, but then the fluffy cheepsters insisted we take them home immediately. Housed in a dog crate, they seem very happy and energetic right up to nap time. This is our first time with chickens, hoping for eggs someday. we are urban backyard chicken farmers with 6 varied chicks. Primarily vegetarian and organic. Can anyone tell me how long they will be comfortable in the dog crate? It is about 3x3x2. The chicks are just starting to show some feathers on their wee wings.
