This morning I opened the coop door and started to break the ice out of the water bowls. I happened to glance over and saw a cat curled up in a nest box! She is one of ours and has been known to hang out with the chickens. I am not sure if she got shut in or if she opened the hinged lid to the nest boxes and crawled in. The nest boxes are an old doghouse that we made into 3 sections and so they are long and can actually hold about 4 hens. The cat and a hen were curled up together in one of the boxes. Cracked me up!
