My Marans chicken had a poop build up and when I cleaned her up, I noticed her feathers had some kind of white growth at the base of her feathers in her rear end area. They almost seemed "spongey" after I washed her. Could not tell if it was the actual feather shaft swollen or a growth on the feather shaft. My other chicken don't show any signs of having it. She doesn't seem ill. Anyone have a clue to what this may be and how to treat?
