Update: Just got back from the vet. After feeling her over, the vet said her crop felt hard and she felt very thin. So her main concern was whether or not her crop is emptying efficiently. She has hardly any body fat on her (breastbone is very prominent). Another concern was reproductive issues. So we did an X-ray to get a better look. X-ray confirmed that there’s no reproductive issues (she’s not egg bound) and confirmed that her crop looks like it might be impacted. This would explain the weight loss and lack of egg production; if she’s not efficiently digesting food, then she’s not getting the nutrients she needs to keep weight on and lay eggs. The X-ray also showed a couple odd, worm-shaped things in her GI tract (the vet said she has never seen round worms on an X-ray before so she’s not sure if that’s what they are). She took a stool sample to do a fecal float, so that will tell us if she has any internal parasites. Also she doesn’t appear to have any lice or mites.
Before I left, the vet administered some fluids to her and gave me 5 syringe doses of Meloxicam to give her x1 per day orally (in case she’s in any pain). She also put in an order for some antibiotics for me to pick up from the pharmacy.
So the plan is to wait for the fecal float results, give her antibiotics, keep her quarantined to monitor her crop/make sure it’s really emptying overnight, and we’ll go from there.
