Hi everyone! I have a flock of 4 hens. 2 cinnamon queens, 1 Americana and 1 Rhode Island Red. For the past few weeks both of our cinnamon queens have been missing some neck feathers. I looked for parasites etc, cleaned the coop well and have just been watching them. Yesterday I came out to let them out of the coop and found literally hundreds of feathers in the coop. Last night when I went to close them in, their run was covered with feathers. (They have a large coop (4 x 6) and a large pen to run in 12 x 12). My kids have been watching them and tell me that the RI Red has been picking on the rest of the flock. It makes sense because all of the feathers that I found in the coop and run were the "caramel" color that belong to all 3 of the other chickens. I closed them in last night and did some research about why this might all of a sudden be happening (all 4 have been together for a year and a half - we did loose 2 of our girls to a hawk attack last winter). Then this morning it was carnage again - feathers everywhere and my poor girls are looking awful! The RI Red is totally fine, so I put up my large dog crate and have crated her in the coop. I don't know what to do! HELP! How long until the other ones get some feathers back? I'm worried that it's November and we have a long, cold winter ahead (I live in Massachusetts).
