Earlier this winter I lost two hens from this, I used pine tar like this site suggested. I have not lost another hen since then. I applied it to the bare spots at first site of blood, kept it on for about a week. I just went out this morning and applied a couple of glops on the new feather spots. Someone had pecked again, but it has been a long while since I had applied any. When I opened the can the hens shook their heads at the smell.
