This is not my hen, rather a friends. We tried soaking her because they thought she just had pasty butt or a build up of poop on her rump. Once we got that off we found this large yellowish clog plugging p her vent it is about the size of a silver dollar and impossible to remove. The vent is being held open by the clog. She keeps soaking her and can crumble away small parts of the clog but I have never seen anything like this. Help?
I apologize in advance for the images.
