I recently (3/18) bought 6 guinea keets from a local breeder who is NPIP. I also bought 3 Cochin chicks from her. I noticed when we got them home one of the guinea keets had a swollen eye. I thought maybe it had gotten pecked or scratched in the box on the way home. He seemed fine otherwise. The next morning, that keet was dead under the brooder plate. All others seemed fine. I contacted the breeder who said she’d replace for no charge. A couple days later we picked up 3 more keets. When we went to pick up she had an older Cochin chick in the brooder who had a swollen eye and was noticeably sick. That day when we got home with the 3 New Guinea keets, another keet was dead in the brooder. The rest have been fine since. Now today, one of the Cochins has a swollen eye. He’s eating and drinking and so far seems fine. So now I’m freaking out and I’m kicking myself for thinking I brought home something that could affect my other birds. I’ve got them in the same brooder as 8 Buff Orpingtons and 8 bantams (purchased from TSC). I’m hatching new birds out today and tomorrow. What should I do? There’s no smell so hopefully not coryza. What else could it be? I don’t have access to a bird vet around my area. Any help is greatly appreciated!
