We have 2 sick chickens. It started with one that I noticed was roosting and had been in the same spot for 2 days and the second day her eyes were swollen shut. So we quarantined her and gave her some Tylan. While we were taking care of her my husband noticed another chicken that was lethargic but not as bad off. Her eyes can open, but she’s often in the same spot and usually has her eyes closed. So we quarantined her as well and gave her some Tylan as well. The first chicken pooped out some barely digested corn, has refused fresh pancakes to eat, and is much the same on her 3rd day of quarantine. The 2nd chicken is pretty much the same. We’re not sure what to do next.
