I have a mixed flock of 12 four week old chicks - 6 ee's, 3 barred rocks and 3 australorps. Just in the last week one of the australorps started pulling feathers and eating them from four of the six ee's. She seemed to leave the barred rocks alone and her fellow australorps. Now, one of the other australorps has started the same behavior and is going after everyone. I've given them a chick stick, let them outside for a couple of hours a day in the garden since it has warmed up here, give them treats to peck at and increased their 18% starter to a 20% protein starter. At first I thought this was working, but they've gone back to the feather pulling and they are drawing blood and leaving bald spots on backs. I have three girls painted with blukote, but they still seem to go after it. I have the two offending australorps separated now and I was wondering how long to do so. They are extremely unhappy being separated and make a lot of racket about it, but I've got to protect the other girls. Since they are still chicks, is there hope to break this habit and how long should I leave them separated?
Thank you for any help!
