Since I started posting here, she's just not ate, and really acts like she's grunting - I put her in the box, she's laying up against the side, and you can see her grunting. I'm really worried now and again, these photos are a little gross, but this doesn't look like poop ...
Ok, it's hard to tell from the pictures. It could be fecal matter blocking the vent, or it could be an actual prolapse. If soaking her doesn't help to pass what's in there then I suggest you follow the suggestions when searching this site for prolapse. An infection generally will be rather red, oozing, and swollen. Good luck and best wishes.
Oh no! i've been thinking about you and her all evening while I've been out, and hoped to come back to better news. Crossing everything that she rallies and feels better soon
