I don’t know what my pheasant caught from my chicken but he’s not doing well last week his forehead got a bump then burst into a lesion. It’s been healing but his beak is turning black and looks like it’s thin and chipping away. Yesterday his beak itself formed a yellow bump then today it burst now his beak has an open wound? The flesh is grey and wet underneath. I don’t want his whole beak to fall off on me can I save him? He’s not breathing well either he always has his mouth open trying to breath and he sneezes and wheezes quite a bit too. Do I try to get him to the vet can anything help him? I had two chickens with Mereks in the past one had to be put down due to the paralysis reaching her lungs but the other is alive and a bit lame but alive and not actively sick. How do I get my pheasant out of this period of active sickness??
