So I was outside feeding my chickens, when the top hen mated with the a pullet. Something came out that looked like a prolapsed vent. I know hens mating with other hens can mean that they are trying to show dominance, but the hen also hasn't laid eggs for a couple of days. I worry that she might be changing hormones since there is no rooster in the flock. What are more signs that this could be it, and is there any way to break it?
