I have been watching this hen for a few weeks now, she has never let me catch her. She has been excreting water, the sound it makes is hissing, like she is straining to push out. Her back side was dirty but I could never see the extent of the problem. Until this evening. I managed to grab her in the coop where she sat and She was easily accessible. Her cloaca is completely blocked with dry poop, and enlarged to the size of an egg. She is soaking in warm water now so I could loosen whatever I am seeing; I don’t want to grab and yank anything out and injure her. Here is the picture attached. Has anyone seen something like this and what can I do next?
