You could grab her out of the nest once you have a cage fixed up.She’s in the laying box now so I’ll leave her be till she comes out on her own then bring her inside. Don’t have a crate but I have chicken wire so will rig something up. And you’re right there’s definitely a tear. Will this heal if I keep giving her Epsom salts baths and oiling the area? I read you shouldn’t try to insert it back in when there’s still hard black parts on it.
Get the wound healed...might not be a prolapse but swollen wound tissue.
Try to get some antibiotic ointment....most households have some around.
