I have a 3 year old white leg horn hen named Fred. She is a faithful egg layer. Last week she stopped laying and looked like she was constantly trying to poop and making a mess on her underside. Yesterday she had lots of blood coming out of her vent...so i gave her a warm soak and rinse..gave her some vitamins and put first aid cream on her vent. Today she isn't bleeding but shes looks like shes trying to poop so hard shes prolapsing herself...its poofing out like 2 red inflamed balloons . I can't feel any egg....shes pooping...so much shes a mess...but not all of it is runny...I saw her push a solid poop out then do the balloon butt thing....she's out away from the other chickens. What ese can i do? whats wrong with her?
