You all are amazing!! I'm so grateful for your experience and help.
Today the vet prescribed: "Albon Suspension" (antibiotic, same as sulfadimethoxine), "Fluconazole" (anti fungal), and "MetCam", an NSAID for pain and inflammation. Given these meds,
@Wyorp Rock, do you still think I need to pursue amoxicillin, Corid, and Miconazole?
I have calcium carbonate in powdered form. The on-line citrate products dosages seem to range from 150-1000 mg per tablet. The powder I have tells how much is in a 1/8 tsp w/ dosage recs for a human. I've seen in this blog the calcium gluconate dosage for egg bound hens as 100mg/kg. Might that be a good guideline for the carbonate powder? I can mix w/ water and inject into her beak.
Vet thought her crop was "squishy," but no odor coming from crop nor vent. The vet tech thought there was some granular material in crop in addition to squishy. Based upon the excellent article provided, it seems that she might have an impacted (vs sour) crop. I will chill some olive oil and try to get some down her--I guess it needs to be a lot--2 teaspoons. White pasty material continues to seep out of her backside, as can be seen by the picture.
I live in a very small town w/no drug stores and only BomGars (and the big city takes a half a day of travel). I can go to big city if necessary tomorrow, but I have vaginal cream here and I think everything else you've recommended.
Any input you have on the meds I was given and the ones you recommended would be greatly appreciated. If the meds prescribed are adequate, then it seems I need to add the calcium for possible soft egg passage issues and olive oil for possible impacted crop.
Vet emphasized keeping Bernice separate, but she is in a tiny laundry room and I think she is lonely/bored/scared. The 4 other hens show no symptoms at all. The controlled environment definitely helps me to administer the medicine, since I don't have another set of hands for holding her while giving medicine, and I don't think I could manage that out in the coop/run. On the other hand, I wish she could be with her friends in a more normal environment. I haven't handled her much at all and am not confident I could transport her back and forth from run to laundry room. I just offered her some yogurt; she got up slowly, turned in a circle, then faced the wall (away from me and the yogurt). Not sure she's up to being with her friends. I hope the isolation won't be bad for her.
She seems to be drinking a little bit but not eating. She fought me pretty hard while I gave her the meds, so she still has some strength in her and she is ambulatory but disinclined to move. I think I am terrible at this, as I hate to touch a bird that doesn't want to be touched. Poor thing is just hovering in the towels, trying to keep herself safe. I hope I can get the syringe of calcium + frozen olive oil inside her beak. I hope this will not cause further stress and fear. Her eyes seem clear, her crown and wattle seem red, and her gait is normal tho very slow. Demeanor is frightened and depressed.
In answer to your question
@Wyorp Rock, she's been eating grower food (18% protein, 1% calcium), with oyster shell and grit on the side--all free-fed. No idea whether she availed herself of these in the past, but I have included these in the laundry room, along with her feed.. I do have organic layer food I could give instead (16% protein, 3.8-4% calcium). I will find out about medicated food, as I have none of that. For treats lately they've had some apple, strawberry, scratch and unsalted peanuts. They also get some soldier fly larvae once a week.
Sorry pics are blurry, taken with laptop and camera makes a startling noise each time.
