We moved our chickens from their warming room to their new coop last week, and we have noticed that one of our CM roos was limp. He limps when he walks and will rest his bad foot/leg on his good foot when he is standing. Initially we thought that maybe he might have been injured in the move but after a week, he is still limping. Now his brother is doing it too. They are eating great and are able to get in and out of their coop OK. It hurts to watch them limp around though. DH thinks it's because they are so fat. Any ideas?
