My hen had a sinus infection that we noticed August 15. Got antibiotics and the swelling went down. She's been on them off and on since then. After about 3 weeks she started eating in her own again. She lost a bunch of weight and went down to about 2 lbs (started as a big fat healthy bird) she has gotten any bigger, still eats and drinks on her own, she's up and around throughout the day but still keeps her eyes shut 95% of the day and they are a little watery all the time. I'm just wondering if any one has had this with their chickens. It seems all that's gotten better is her swelling, breathing and eating. She stills walks all stumbly and we believe she's partially blind in one eye now (doesn't quickly react when you swat towards it) Is there anything else I can be doing to help her feel better? Photos attached were taken August 16.
