My astra. hen has had a watery diarrhea this last wk so today I caught her and was going to wash her up and when I got thru the feathers by her vent, I found the vent was wide open the size of an egg but appears to be impacted with poop. I've been soaking her in warm water but cannot get it to budge. Is it poss. this could be a "broken" impacted egg with poop around it. It is adhered to the walls of her vent so tight I'm afraid I'll hurt her trying to pull it off. Any ideas re soaking or putting oil in to soften. I soaked her for about 30 min. and it did not soften up much. I really do not want to cull her.
