My chicken - Gretchen - was attacked by a raccoon and badly hurt. She had a large silver dollar tear over her thigh, and it finally got a scab, but would not heal. I read that I should remove the scab. I did, partly, and it healed a little more, but a new scab has formed. Also, she had a large section where the feathers were torn off, and the skin was pulled off the breast. I took her to the vet and he said that the skin would heal, put it 'puckered up' and hardened and then pulled away from the other skin. So if you press at all on it, you can see the muscle of her breast. When she first was hurt, I had left her outside separated from the other chickens. I did not know about flystrike. Sure enough, she got all these maggots. So nasty. I had to pull them all off with tweezers, (over 100!), but I knew many had gone to 'dead space' under her skin. So I took her back to the vet. Meanwhile, it's been a month! And she has not healed. She has this very big 'scab' from the puckered skin and the skin does not appear able to stick to it. I'm so worried she will get flystrike again. For a while I kept her in the garage in a dog cage wrapped in screening. But she seems perky and misses the other hens. So I have been letting her out for short periods during the day. Do I just keep waiting? I don't think it's infected. But I wonder when on earth she will be finally healed. She I pull or cut the 'scab off'?
