I have a pet chicken, a 1+ year old Rhode Island Red, that has a rashy chest and has grown a red, soft mass on her featherless bottom. I feel this has happened in the last couple of weeks as I can't imagine not noticing the red bottom before. I inspected inside her vent for a bound egg, but could not feel one and she has been laying an egg daily. When I got this hen as a pullet, she presented with chest feathers missing and they never grew back -- she was crammed in a cage with several other chickens and I figured she was just the lowest on the pecking order. She now lives in a large coop with one other Rhode Island Red; their "bedding" is scraps of Bermuda and alfalfa hay and dirt. Her coop-mate does not exhibit the issues exhibits. Both girls are allowed several hours of roam time around the property with supervision. Over the last several weeks, the hairless red bottom seems more pronounced. (Incidentally, it will sometimes be bright red and the next normal skin color). I read a lot of the messages on this board and other boards with people having similar symptoms of a red, swollen, featherless bottom. Some of the thoughts were a bound egg, mites and prolapse. Outside of my own hen's bottom and rashy chest, she is alert, runs around, eats, drinks, lays eggs daily (bless her heart). So I took my hen to the vet yesterday and they took a side x-ray and skin scrapings from her chest, vent area and bottom area. The skin samples showed nothing (e.g. no bacteria, no parasites). The x-ray on the other hand showed a mass around the vent area and the doctor thinks this mass is pressing on her small intenstines which are the soft, bulge she is presenting on her bottom. He is not an avian specialist, so is referring me to one, as he admits this goes beyond his area of experience. I wanted to share a photo of the x-ray with you for your input. I would greatly appreciate your thoughts. This is a pet and I just want to be proactive on what this "mass" is and what options do we have (if any). Again, her respiration presents fine, she's alert, runs around the yards scratching the dirt and all, is laying eggs every day, has clear eyes, has hearty appetitie, drinks water and poops fine.
