I really dont know what is going on with my flock. The first sighn was in my Jersey giant where I thought the hens were picking her back neck feathers. Well no blood or peck marks just "pin feathers" in place of the feathers she had on her neck(she is almost 6 months old) Then.... My Partridge silke, we call her "Fro"chick cause of her big fluff on her head. Well that big "Fro" is going away and causing her to be bald and she is only 7 months old!! No pin feathers here just baldness(we really miss her fro! ) Now.... My frizzle NN hen is starting to go bald on her back with just pin feathers. What is going on??!?!?! I hope someone here can help. Thanks in advance!
