We have a small mixed flock at our school. One of our students noticed a hen with a particularly dirty butt. When I checked her, her vent was nearly blocked by dried poop. I cleaned her up, but the tissue surrounding the vent was red, swollen, and bleeding, so I have separated her. Each time I clean her, within 24 hrs. poop is sticking to the tissue around the vent again (not sticking to the feathers, sticking to the tissue immediately around the vent). I have been alternating putting neosporin and Amoximast on the tissue around the vent each time I clean her. She is eating (Layer Crumbles) and drinking fine. Any suggestion on how to break this cycle of the poop sticking? Thank you!
