The other day I went on the behavior forum and ask why my Chickens started plucking each others bum feathers out and eating them. I was told the were lacking in protein. Now 2 of my girls have a completely bald bum! What should I do about this? They are 7 months old, they are being fed laying feed, and I feed them oatmeal mixed with sometimes fruit or vegies or yogurt. They have fresh spring water everyday. Because my well is tapped into a natural spring, not because I buy bottled water! And they lay almost everyday! The past 3 days I have gotten 11 eggs from 11 laying. Oh I feed them pulverized eggs shells mixed with their feed.
