There have been some coyote's around our neighborhood lately, and as you can imagine our chickens have been on their menu. A few days ago our chickens started getting eaten, we thought our rooster was one of them because we we kept seeing a lot of feathers that looked like his in the trees behind our coop, but today we found our rooster again. He's not very old, we just got him this spring. When we found him his back feathers were really ruffled and he was limping. What can I do to help him heal?
