At first I thought my chicken was being pecked and it was skinned,bloodied places but have noticed it is spreading all around her waddle and comb? She is a Rhode Island Red. None of my others seem to be affected, only one hen. Her comb and waddle have also started turning pale. Anyone know what this could be? We just built a brand new coop. I haven't noticed any other changes in any of them. It has been very cold and wet here in Northeastern Oklahoma. But the coop is dry. They are all roosting on the high roost every evening. They free range all day. A hawk murdered one of my chickens 2 weeks ago but no other trauma that I know of. I just noticed this a week ago and noticed today it seems to be getting worse and spreading. Thank you for any help anyone can give me.
