i removed this from my easter egger Xena. It showed up the same time my flock got avian pox. It got huge and ended up consuming her face. I cleaned it today and it started coming off in yellow chunks (you get the visual because i got it under my nails). Ive been wiping it and dousing in ointment. Everyone else cleared up-Xenas got worse and she got listless. It came off with a little persistence and a swipe on the top with a scalpel to make sure no blood vessels are in it. this is xena post surgery. Yikes, right? The mass has pollops in it, like it was a cluster of mini masses and infection. It has hardley bled, so little that a white towel did not stain. Shes a little droopy but pooped and drank water-shes being monitored as i type. What in the hell did i just get off my chickens face?!
