I recently added these little buckets to my chickens roosting area but I went to check on them one night to see how they liked it. Only half of them sleep in them. The other half I found sleeping on top of the ferret cage we use to integrate new chickens with. As long as they are comfortable I suppose it is not a big deal where they sleep. But my concern comes in when they start laying. Will they prefer the black buckets as a nesting area when they start to lay?
