Alright, so, I've done quite a bit to fight off this whole ordeal and nothing I do seems to be working. I bought a few chicks from Tractor Supply a couple days ago. Boosted their water with Probiotics, just a smidge of ACV, and just plain ol' water. Moved the heat lamp up, noticed they were too cold, moved it down, seems a little warm but they're not all clumped up anymore and spread out somewhat evenly. Still, the pasty butt continues. Sparingly used vaseline and mineral oil. Now I've got one chick that cries loudly and won't stop, and it's vent looks rather swollen. Treated it with iodine for the moment, but it's not really quieted down. What is the best way to stop the pasty butt? Seems like every few hours I'm soaking and cleaning butts, applying vaseline/oil, and repeating. Never had any problems with pasty butt before... All of my chicks have been bought from small farms, not hatcheries.
