Long story short, I think I have two hens who have mild vent gleet. They've both stopped laying, have slightly swollen abdomens, messy feathers on their bum fluff and loose stools. Both hens are 2 1/2 years old, and I know I need to deal with this now since I recently got a rooster and I see no reason why he can't spread the yeast infection from hen to hen. Does anyone have ideas for treatment of vent gleet? I've done reading, but I'd love to hear treatments that have worked well for other people. I know I've taken Tanalbit (Tannin formula) for yeast infections and it's worked well--is this safe to give to chickens? I have some on hand and can start treatment right away if this is okay. Thank you for any and all advice! I've all ready been giving them vinegar in their water, and that's probably why they haven't been extremely sick yet.
