This is so embarrassing I am afraid to post. I have about 5 week old chicks in a rabbit hutch. I laid a piece of carpet in there so their little feet wouldn't fall through. One must have scratched at the carpet and loosened up a thread that looks like fishing line. The line was wrapped around like one toe i got it off but the toe nail looks like it is dying. Blister on foot too. I cleaned it and put antibodiac cream in both feet. I have been out of town for two nights nd DH was in charge. So I don't know how long she was wrapped up in it. What should I watch for? Should I be doing something else?
