Well, we ended up taking Gurtrude to the vet because she wasn't eating and her abdomen was really firm. Turns out she has a broken shell in her reproductive system and had 378 mL of fluid in her abdomen. She's home with Ceftiofur/Naxcel and Meloxicam. Her regular vet isn't in till Wednesday, so I'll be talking to her then about getting her spayed in the next month or so. Until then we just remove the fluid as needed and give her her meds. It's a good thing that eggs aren't a requirement for room and board, she's such a sweetheart.
