My hens are relatively self sufficient. I feel bad for not catching this sooner but we snagged a couple gals to put into a chicken tractor to do some tilling. When we were carrying one over we noticed she smelled terrible - like rotten terrible. So I turned her over and she has yellow crust/ooze on her vent. I soaked her in epsom salts and then snapped a couple pictures to get help IDing the problem. From what I have read this could likely be vent gleet. But, I don't want to avoid antibiotics if it's a bacterial infection and I don't want to give them if its fungal. Also, this is post butt-soaking so that's why her feathers are super special. Thanks for your help. And, any suggestions on how to deal with this are greatly appreciated. I already give my flock apple cider vinegar in their water and recently did an epsom flush for everyone when I switched them to a new coop/area (my old coop had mold in it that I worried was impacting their health).
