Hello, My flock of girls (no roosters as we live in the city) was beautiful and healthy up until about a month ago. Then one of my black australorps came out onto the run with a bare behind. We could'nt figure out what was happening because I never saw her get pecked! THen others began to look quite ragged but never bare and so I looked in the chicken book and it said good layers should have rather beat up looking feathers, and my girls are amazing layers! They all appeared healthy, eyes bright etc. No mites were/are present that I can see. When I called the hatchery they said not to give them corn. Although I don't, my tenent would give them corn on the cob a few times a week. I asked her to stop and began giving the chickens extra protien but the pecking hasn't stopped. I let them out a few time a week for a few hours but can't continue much longer because they destroy the flowers and the garden. There are 16 chickens in a coop that is15' x 5' (It is a converted snack shack from a high school) and their run is quite big as well. I can't bear seeing them peck each other and its getting worse. I'm considering getting rid of them if this is going to be common problem. Any help to make them stop would be greatly appreciated! Thanks! Desparate, kmscala I miss my beautiful chickens!
