I have a little black bantam hen in a big cage in the house. She lays one egg a day and is very active. So today I reached in to get the egg she just laid within the past hour and noticed her rear end appeared to be stopped up with "poop". The rear appeared to be "inside out" and dark red. More whitish poop was on her feathers around her rear. I got some rubber gloves and cleared the stuff out gently. Wiped off what I could. She did not appear to mind my intervention or be in pain. Is this normal to happen occasionally? Is it a "food" or "water" problem perhaps? All ideas appreciated!
You might also give her soluble antibiotics in her drinking water for about 4-5 days to guard against infection.

"Prolapsed Oviduct, also called "blowout" or "pickout" is a condition in which the lower part of the hen's oviduct turns inside out and protrudes through the vent. Prolapse occurs most often when a hen starts laying at too young an age, is too fat, or lays unusually large eggs. Caught in time, the prolapse can sometimes be reversed by applying a hemorrhoidal cream (such as Preparation H) and isolating the hen until she approves. Otherwise, the other chickens will pick at her vent, eventually pulling out her oviduct and intestines and causing the hen to die from hemorrhage and shock. Not all vent picking is due to prolapse, but instead may result from faulty management - feeders, waterers and roosts may be positioned in such a way that birds below can pick on the vents of birds above."
