We have an older rhode island red (maybe 4-5) not sure if she actually lays anymore, eating and drinking normally, but not quite as active as she has in the past. I noticed that she was missing most of the "fluff" on her underside, and what I thought was dried poop. Upon further investigation, I got her out to clean up the poop with some Nolvasan scrub, but it wasn't poop after all. Don't even know how to describe it other than what appears to be necrotic skin/growth below the vent. Also that entire area below is red and irritated looking. I will take a picture and upload tomorrow, but wondered if anyone could give me a clue as to what's going on with her. I flushed out the skin/wound and flushed out a maggot! UGH! I applied Neosporin to hopefully keep any other flies out. Help! Thank you!
