See my previous post: https://www.backyardchickens.com/forum/viewtopic.php?pid=6818726#p6818726 Pullet with damaged vent. Looks like it's starting to form a scab, but vent will not close, not enough skin is left. She keeps "farting" and the poop just sort of falls out of her. Will it grow back? Where is the gas coming from, I've heard chickens don't usually fart? After she farts she makes a distressed noise.
