So this all started (well from when I first noticed it) 2 days ago. I have a Barred Rock hen a little over 15 weeks old. She started keeping 1 eye closed & staying away from the rest of the flock. She acted like she was tired & did not want to exert any energy. She was still getting in and out of the coop fine, but just seemed like she just wasn't feeling all that great. We live in Louisiana & our temps recently have been 95 degrees +/- a few lately. We took her away from the other girls yesterday and I had to force syringe her water & she ate a small tomato and some boiled egg. But that was it. All she wants to do now is close both eyes and lay down. No eating. No drinking. Her poop does not seem right either. No sneezing. No drainage. No swelling. Her feathers seem a little puffed up and her chirp just sounds blah. Not perky at all. Please help! Don't know if its viral or something I should treat with antibiotics. All other hens & a roo are doing great! I attached some pics to try to help diagnose.
