One of my Ameruacana hens was bleeding fairly heavily from her vent this morning. She had a few inches of "intestine-like" material, I'm assuming her oviduct, protruding as well. She was crouched, not moving, and let me walk right up and pick her up. She was one of my most skittish chickens and never let me handle her, so that was unusual. There was blood in the nesting box (but no blue egg) and blood drops around the perimeter of the coop. I opted to put her down, but now I am questioning myself for doing this. I had never previously had such an issue in almost 2 years of keeping chickens. From looking at past posts I suspect a severely prolapsed oviduct. I noticed one of my other hens, that allows me to handle her, has a small red protrusion from her vent- like a small cherry. She seems fine otherwise and is acting completely normal. They get fed a laying mash, oyster shell and kitchen scraps, mostly fruit and veggie scraps. Is there a condition that could cause more than one hen to prolapse, or is it just coincidence? And, most of all, did I do the wrong thing by putting the bleeding hen down?
