One of our broody hens hatched a group of 10 or so chicks, combination of different breeds, even a few Bantams came out of this nest, used by at least 4 hens. Now 3-4 weeks old some have developed an eye infection; first 4 came down with it, one eye swollen shut, or almost shut, forming a crust, and leaking. Because of the cold weather, we had them in a small pen with a towel on the floor.When we noticed, their feet were getting poop caked on them, then they would scratch at their eyes (maybe the cause???). Cleaned them good, isolated the sick ones, moved the rest to a tractor. Treated the sick with salve that vet had given us for our dog who by coincedence also had an eye infection. Also put terramycin in their water (2 tsp/ Gal.) after a few days, they all cleared up, & were also moved to the tractor. Now 4 different ones are infected- one eye only. Two have one eye swollen shut, one has a crust covering it's eye, the other one's eye is shut, & leaking, 2 have what appears to be a swelling of the upper eyelid, similar to a boil. Three days since we isolated these, & no improvement. Same treatment,in addition to a nasal saline solution. Did a search on eye infections, not much help. One of the "healthy?" bunch died, didn't appear to be infected. Can our dogs problem be related? Wife says it's pink eye, (whites of eyes are red) one vet said no, thought it was eyelashes under lids, second vet didn't know, both know even less about poultry, but both said they didn't think the illnesses were related. Dog doesn't appear ill, just the red eyes. One vet perscribed a salve which helped, but then redness came back. Thourghly confused, don't have any idea how to treat, & worried this may spread to rest of flock.
Sorry for the long, rambling post, but trying to give as much info as I can. Thanks for any help/suggestions.
