i Have 2 roosters and they despise each other. While in his hard metal cage, he tried to peck the other rooster who was walking on the floor and in doing so, his beak hit the hard wire, literally smashing off the top keratinized layer of his top beak, like when one loses a nail. His top beak is totally tissue now. I believe he’s in a lot of pain. I gave him some meloxicam and applied theracyn to his top layer. He won’t eat nor drink water. My question will his outer, keratinized layer grow back? How should I manage him? Should I take him to a vet? Please advise. I love my rooster, he’s been my savior since my mom passed away. I can’t see my life without him.
