I have a hen, she's about 4-4 1/2 months old. She's had labored breathing, when she clucks (or squacks) it sounds like she's got gunk in her throat. I'm really worried. Her crop is completely empty but she won't eat. She won't drink anything, either. I tried putting her in isolation but it only made it worse. She seems dazed. Like she's sick. I don't understand it. Please help! She hasn't started losing feathers, but I think it'll be soon unless I can figure out whats wrong. She's an Americauna/Rhode Island Red cross. Thanks!
