For goodness sake! I've lost 2 of my girls to some unknown wasting illness, one to a fox & have just found one of them with, what looks like a prolapsed egg vent! Didn't think keeping chickens was supposed to be this stressful (& expensive!) Off to the vets soon with the prolapse, atm she is in a separate coop, looking all sorry for herself. I've not even had them for a year yet.
