My Americana chick has had labored breathing for two days with sneezing. It gets so bad that I’m sure she is going to die soon, but somehow she keeps pulling out of it. I’ve never seen a chick fight this hard. She’s eating and drinking and still running around. I’ve changed bedding, been doing VetRX, been giving electrolytes and probiotics in water, and medicated feed. Is there anything more I can do? Do I need to find antibiotics? She’s my favorite chick so I want to do all that I can. TIA.
