What are chickens missing in their diet if they are plucking feathers off and eating them? I have three bully chickens plucking out feathers off of other chickens. I put up outdoor perches today and two hanging seut baskets also. They have pumpkins, scratch, pellets, and plently of water. Their run is plenty large. They have leaves to dig through as well. Their coop is kept warm. They don't sleep next to it though. They are laying ok. No light on a timer so egg production has gone down but that's ok. They also have oyster crumb to peck at. What is missing? Should I remove them from the flock? Should I add a rooster? HELP!!!! I ordered peepers but I'm afraid they will kill another one before they come. Any suggestions?
