I picked up 5 little chicks last week. 1 Buckeye, 1 welsummer, and 3 Cochins. Most things seem to be well, but I have one little Cochin chick that is really mean to the others. She pecked one near the vent till she was bleeding, I separated the injured and cleaned up her pastey butt thinking that was the issue. Well the next day she seemed to be pecking another. I moved them into a larger box. And they seemed fine for a few days, but yesterday she started pecking on everyone. She pecks 1 near the eyes. And 2 others on their vents. I noticed yesterday she was pecking The last one on her feet. I have tried separating her, but she gets very upset, runs around making noise because she wants to be in with the rest. Do you think I should move them into a bigger box again? I also added a few sticks and things to use as roosts. I've been giving them a littlew bit of sand to scratch around in and have taken them outside for short periods while I clean their box. Is there something else I should be doing to keep her from picking on everyone? Is it a good idea to leave her separate? I don't want her to injure anyone else.
