I'm having an issue with some chicks that I have never run across before. I hatch a lot of chicks, some under broody's, some in incubators. I have silkies, show Girls, Cochin bantams, and my laying flock consist of naked necks and various layer hens. I sell a lot of chicks but I usually wait until they are at least a month old because I have frizzles and they are usually in high demand. In a few recent hatchings I have noticed a trend. Out of 15 to 30 chicks I will have one or two with these symptoms. They are slow to develop, lethargic, and have a whitish discharge daily from their vents. Not pasty butt. It also seems to affect the feathers on their behinds as they become completely bald. Eventually these chicks die or I cull them. It has been my opinion that this is some type of yeast infection and I have been treating it as such. They have clean water that is sanitized often, they live in clean conditions, I use apple cider vinegar in their drinking water, and give them yogurt. I have 2 with this condition at this time. These are the only two out of many chicks. Daily I clean them, give them Nutri drench occasionally and I have tried 2 different fungal creams. Monistat and a jock itch medication. Externally and internally. I know some people say not to give Monistat orally but these chicks are going to die regardless. I know that older hens with crop, and vent yeast can be treated with Nystatin or copper sulfate. I guess what I am asking is if anyone out there is familiar with this problem in baby chicks and how did you treat it? Naturally I'm going to take 1 to a vet, if I can't get this figured out . Also if I need Nystatin I will have to go to a vet . I love my chickens and I sell them so I can keep them as a hobby . I just know that many times other chicken owners have valuable input.
