My chicks are feather plucking, they are going on 3 weeks old. When ever I hear one of them yell, I see another one eating a feather. It appears to be one main culprit. I took him out and put him with some older chicks and they started eating his feathers.
The older white Plymouth rock chicks use to pluck and eat my same age Cornish cross chicks, that's why they have their own pen, but I notice they don't do that to each other. However, they started doing that with the younger chick.
Its a good thing, I identified the instigator. I put him back with the others since the older chicks was pecking on him. The first thing he did when he rejoined his siblings, he plucked their feathers.
I was thinking maybe they need more room to play, so I opened the small pen door, so they can go out to play and eat grass. The culprit may end up sleeping out side, by himself if he keeps this up. I changed their feed to a higher protein, my chick starter feed was 18%, I changed it to a 22% broiler starter.
I have been watching them and I don't hear them yelling anymore and its only been about 15 minutes. I see them running in and out of the coop, they seem to be having fun. I think, giving them the freedom of space maybe the solution.
