I had an issue with a coyote that killed several birds and an owl that also killed some birds which were my Rhode Island Whites. I had a male and two females left to build up my Rhode Island white flock back up with. I shot the coyote but only had bird shot in my gun. It dropped the bird it had but she died the next day. I'm sure I hit it as it took off. With the owl I had fishing line over the pens which was replaced with heavy duty netting. When I moved the birds after the owl attack the male was very bloody and very freaked out and there was blood everywhere. One of the females has a damaged comb, but they survived.
