I'm not sure what happened. Last night as I was getting ready to close my birds up for the night I noticed that one was still outside the fence. I picked her up and put her over the fence and my rooster ( I keep chickens too) mounted her, I'd seen this before and had read about it here. I chased him off and when the guinea hen moved towards the coop I saw that her insides were hanging out. Her vent was torn out and her intestines were hanging out. I also keep goats and the hens were in with the goats yesterday. They were able to push their way through the fence. The hen was healthy before then as far as I could tell. Did the rooster do it? Was she stepped on my a goat? Could squeezing through the fence do something like this? I'm just sick. I want to stop this from happening to my other birds.
