Has any one seen this before all the research I can find looks like one of my hens expelled her uterus. I found this on the coop floor beneath the perch. I have 25 layers in this coop and none are looking ill. Of course I didn't get home until after they had put themselves away for the night so they are all pretty lethargic. I am so afraid this can not be good. I cut it open and there was a soft shelled egg in it. The membrane around the egg is tissue/organ like so I am pretty sure it is the uterus.
