I have a hen that has swollen wattles. The neck seems to be swollen too. She is not closing her beak and seems to be mucus around her mouth. I have noticed her trying to drink but is not able to close her mouth so I am not sure how well she is getting anything down. My husband pulled her as soon as we noticed something wrong (yesterday) and put her in a carrier by herself. My husband said she is moving her head back and forth doing the Stevie Wonder dance with her head. She did lay an egg today. As soon as I figure out how to post pics I have them. The neck today right above the wattles was blue. That can't be good. It hasn't been below 78 at night so I wouldn't think frost bight. My husband thinks it could be a copper head snake.(we have found 3 on the property). We have a friend that his uncle is a vet and he said it could be gape worm or avian flu. The vet has only seen the pics not the bird in person. We are planning on going to get Tylan 50 in case it is an upper respiratory infection. PLEASE if this is wrong let me know. Any help is appreciated.
