we have a JG, about a year old, laying well, happy, but where her back meets her tail feathers we notice a bare, red area like she has been pulling feathers from there. It rained all day yesterday and she was bedraggled and we noticed it more as a result. Noone is pecking her (I spend an embarrassing amount of time with them and we have only 3). Molting? But, if so, should it be red and sort of angry looking? Our SLW has a problem with clearing her under-tail feathers when she poops and we have had to clean that off to reduce the "diaper rash" (which seemed to make her very happy once the deed was done). This looks similarly rash-like. They preen alot...I don't SEE any parasites but could this be something to address?
