So my male kitten attacked one of the chicks. I was right there and he got wacked to make him let go. Pierced through the left wing which bled a bit, and tore the skin almost an inch open on it's sternum/belly. I closed that with two disolvable stitches. I think it will be ok. It was stressing and shaking so I had to give it back to mama. It hid under her for a few minutes then was back out and about with it's sibling like nothing happened. I caught it again and it was acting normal.
