If the only birds there were momma and siblings, I'd say it was the hen. She may be rejecting this chick for some reason.
Don't use hydrogen peroxide. The current medical thinking is it actually harms living cells, slowing down healing. I would get a bottle of veterycin spray. It is amazing stuff, even if a little pricey. You can get it at a feed or pet store (I've even used it on my own wounds....). It is well worth the price and you just spray it on. The gel form seems to stay in place a little better than the liquid (both sprays). Be sure and keep the little one separate, warm and quiet. The other birds will go right back to picking until it is healed and then you will have a little problems with integration. I think as soon as the raw was healed over, I'd see if I could find a smallish chick for company.
Good luck,
Deb
My mom is a nurse who specializes in wound care. H2O2 is good for the initial cleaning, but not for ongoing care. It does prevent healing, but is good for getting a clean wound bed.
