We noticed yesterday that one of our hens, (1 1/2 y.o. Wyandotte) had a bloody bulge near her vent. Yesterday, the bulge was about half the size of an egg, and seemed to protrude. There was a small amount of blood on her outer feathers, which is what we noticed. She isn't a big layer, and recently came off a VERY long broody stage, (Immediately following her molt) where she lost a lot of weight. She has a very fluffy rear, and the feathers had a lot of feces stuck to them. After bathing her in warm water this morning, the bulge is much smaller. I have released her back out in the yard away from the other chickens. She appears to be feeling fine, but I'm wondering if this will resolve on it's own, or if I need to do something to help?
