I have two hens that I separated, along with 4 others because I had a couple bulleys in the coop and couldn't figure out who the trouble makers were, anyway, 2 of them have developed really runny poo. It seems to just slide down from their vent which is making their backsides really slimy and gross. They don't act like they feel bad, in fact, they act like normal, I want to put all my girls together again but until I figure out the runny butt problem, I'm not sure what to do. I did worm them like 4 days ago but they had that problem before I wormed them. If anyone has any ideas, I would appreciate some help!
