Hi, I have three hens w/three eye issues. The first one has one eye that is runny w/clear liquid. Eye drops don't seem to help. She seems to be dusting alot. I see her sitting in the dusting box alot. I don't see mites or lice on her. If I bring her in the house, she is fine after a couple of days. Is there any suggestion on her eye? Is it possible she has mites and I am just missing it? The coop is ventilated, no urine smell and clean. The second one is Penny who was sick a while ago. She has the same thing again. Runny nose and crusty swollen eye. Appears to be miserable. Last time the vet had me give her antibiotics twice a day. A crushed pill in water. He thought it was the Myoplast....word. Sorry can't spell worth a darn. List members suggested it was coryza. Is it strange for her to have gotten sick so quickly? Will she always be a sick bird or am I doing something to cause this? Will the Tylan 50 be good to use? The third bird has one eye that is closed. It started off as having a bit of bubbly stuff in the corner of the eye. Now it is just closed. No crust. Eye drops didn't do much to help. This is a rather petite silkie bantie rescue. ANy suggestions on any of these. I checked all of them for mites and i don't see anything. Like I said, the coop is clean. They get their usual boring chicken feed plus there is a small supply of cracked corn, sun flower seeds, oyster shell and scratch. The dustbox is a combo of dirt, ash and a touch of DE. I use the deep litter method w/hay. I am new to all of this and am sure even dispite my best intentions, I am making errors. (Motherhood but with 10 instead of just one!) I am bothered by all of this and I don't know if I am doing something wrong or if I just have a poor flock of hens. Most came from a local farmer that kept them in unclean conditions and fed them only cracked corn. Thanks all!
