Feather picking can become a habit. Three reasons they do it are a lack of protein from feeding less than 16% or too many treats or scratch, too little room when locked up in a coop and run, and not enough to do creating boredom. I would try some 20% all flock raiser type feed or 24% gamebird feed for a little while. Then I would place some things for them to climb on and explore--roosts, big rocks, tree stumps, a large piece of sod, and a nice dust bathing bin filled with sand, dirt, and a little wood ash. And make more room--sometimes that means re-homing birds. Be very careful mixing new birds together, and PLEASE quarantine all newbies for at least 30 days to make sure they are not sick.Hi, I'm new to BYC Forum. I have the same problem and was wondering if it was related to the breed of the bird? I have 4 Austalorps, 6 Red Comets (which I think are a prouduction bird) and 3 EEGs. The Lorps are big enough to hold their own, but do have a few small bald spots. The Comets are very aggresive and have most their tails are striped. The Little EEGs are being stripped by both the other breed. I have tried everything and am sure wintertime boredom is the problem but can't seem to get the right combination. Do you think trading out the RCs would help?
