Hi I know this is a chicken site but I have a female duck I suspect has vent gleet? She has a white discharge and before I cleaned her up is was like paste now the she has pieces of it stuck around her butt that reminds me of tiny oyster shell pieces that I can’t get off of her without pulling her feathers out. She is eating, drinking, and acting normal. I am treating her internally through her vent with monistat and I have added probiotics to drinking water. I am attaching a picture it’s before I cleaned her up. Is this vent gleet? If so how long does it usually take to clear up?
