I have 5 layer hens. They've been together since they were hatched. First we had roosters plucking their backs bare, so I got rid of the roos, then we had a 6th hen plucking their backs and heads, she's gone. They are still plucking each other and I've tried everything. Better food, more treats, less treats, Blue Kote, even built a bigger coop for them. It is so awful to look at, there are no mites, lice, etc, either. What to do in this situation? DH wants to throw them in the pot and start over in spring. Also, they stopped laying when we moved them to the bigger, nicer coop. Ugh!
