I noticed a bare spot and scab on the backs of one of my 3 RIR's. It first appeared about a month ago and it looked as thougn she had gotten pecked. I put ointment on it a couple of times to help it from drying out but it remained. Now this morning, after a week or so of feeding at night I finally got good look at the 3 of them and this poor chicken is in bad shape! Please see the pic. She has lost a lot of feathers, has trouble walking and standing and looks as though worms are growing out of her back. Can this be cured??? Thank you!
