One of my broody's new babies has been attacked by the adults. it now has several bloody spots, including a large one under the wing where skin might be missing. the chick is still active and peeping, and i've seperated momma and the other chick. How do I treat the wounded chick to keep the mom from hurting it? Should I cull? Please tell me to give it a chanc, i can't bear culling the baby. Whay can I put on the largerwound to seal it?
