Update:
It's been almost a month. We never ended up using Enrofloxacin. She was on Sulfatrim almost a month. Once she stopped laying, she seemed like she was getting better, but now she seems unwell in a different way and I don't know what to make of it. She's had fluid infusions with the vet 1-2 times a week to make sure she's hydrated. We have been tube feeding her medicine/emeraid with nutridrench, probiotics, and b12, 2x a day. After she went out of lay by reducing her photoperiod, she seemed to be doing a bit better- talking to us, jumping up to roost on things, eating bugs we gave her. But then, she has stopped wanting to eat things. I would introduce something new, and sometimes she'd pick at it. But she won't eat her solid foods (kalmbach pellets, seed mix, harrison's) nor the insects (crickets, black soldier fly larvae, mealworms). I don't know if she doesn't want to eat because maybe her throat hurts from the tube feedings, but she's not on meloxicam anymore so it's unlikely that her tummy is upset. She will look at food, then shake her head as if it smelled bad or something. She has been less active, just wanting to go to sleep in the corner, she has her eyes closed a lot, and kinda shakes her head. The vet thinks she's coming out of things but I am skeptical because of her behavior change. We started bringing her outside for a few hours to get some sun and be able to dust bathe the last few days. She was interested in eating some weeds, but nothing else. She has another fluid appointment today. I just feel like she's going downhill the way my last bird that passed did, back in December. She got through the painful part and we stopped her laying by keeping her inside, but I don't know what is wrong that she won't eat and is still passing mostly urea stools. I was a little worried that the sulfatrim had wiped out her good gut bacteria. We've been giving probiotics with her tube feeds, but benebac avian is no longer available so we had to switch to a new brand (we've tried 2 since then and the vet doesn't really like either of them). Lemme know if anyone has any thoughts.
