Hi, I am new to chicken raising. Got 8 Isa Brown last week, between 18 and 20 weeks old. Noticed that one chicken was not moving much with eyes closed most of the time. Also noticed that she was bullied. She will not drink. The only way she gets hydrated is when I give her watermelon. She only eats if I wake her. I did let her loose, and she would peck a bit on the ground, until she finds a spot to sleep. Decided to move her from the flock after a few days. She is now in a cage, and I make sure to feed her many times a day. Her poo looks good, sometimes watery, but most of the time ok. We are giving her polysporin in the eyes for the last few days, but does not seem to improve. Now, she is starting to scratch her ear lobe, and its starting to be a bit bloody. I did call the store where I bought her, but they have no solutions. I took a photo of her eyes, seem to have some kind of film over the iris. I do not want her to suffer, so we are thinking of putting her down if she does not get better, unless someone can enlighten us, and can offer advice. Thank you!
