My five-year old Black Cochin Morgan, the biggest, roundest fluffiest Cochin you've ever seen, was literally carrying her egg around stuck to her fluffy butt feathers. At first glance, nothing seemed different about her fluffy butt. I was on my knees raking under the coop, and Morgan zeroed in like a guided missile, demanding a hug. As she dove between my legs, I caught a glimpse of something large hanging from her butt. At first I thought it was a turd since she has ridden those around before on her butt feathers. Then I thought, to my horror, it's a prolapsed vent. I parted her thick butt fluff and there was a perfect egg glued there. I think she was aware of something heavy hanging off her butt because she was complaining very loudly, and it stopped after I liberated the egg. I'm surprised none of the other hens went after it and liberated it first. No matter how long you've been keeping chickens, there's always something new.
