Update over here:
She made it through yesterday and last night. Yesterday she stayed mostly huddled in her hidey corner all puffed up and looking like she was trying to pass an egg. However, she would come and eat from my hand and then drink when encouraged, so I just kept doing that every hour or so to make sure she didn't get dehydrated or anything. She wouldn't eat her regular food, but would eat sesame seeds, meal worms, and a little bit of kale and apple so I just kept feeding her a bit of that stuff - didn't want to overwhelm her system with treats, and also didn't want to fill her up in case that would cause her not to go to her regular food. But I figured something was better than nothing and she would only drink if she'd been coaxed out with those treats and that seemed like a better way to keep her hydrated than to keep taking her out and forcing a dropper into her mouth and stressing her out.
At one point last night she even went into her sand bath and scuttled around a bit. We put her to bed with the heat and humidifier on and hoped for the best.
This morning I was dismayed not to wake up to her usual calling (she usually makes a lot of racket when the sun rises, kind of sounds like a rusty gate) and went out to the kitchen braced for the worst. To my relief, when she heard me come out she gave me some nice friendly chirps and ate some sesame seeds from my hand again. This morning she seems to be in better spirits - moving around a little more and not appearing to be sitting and straining as much. She still hasn't really touched her food but I will lay off the treats a bit and see if she gets hungry enough to go for it.
This is all a puzzle - I've searched the aviary for any sign of an egg passing and can't find anything. Her belly looks smooth and small, not like there is an egg inside of it, and I've not been able to palpate anything that feels like an egg, even when I've searched inside the cloaca. I'm increasingly suspecting that she is not egg bound and something else is awry. We examined her poops last night and some of them were a bit strange - they had a greenish-yellow tint to them with black spots that may have been partially digested flies. Our new hypothesis is that she may have been having a hard time digesting the flies and that led her to a great deal of discomfort when pooping...still she pooped a lot, and the consistency was pretty normal so I'm really not sure.
We definitely are not out of the woods yet.
If anyone has any ideas about what could be happening or how we could keep helping we would be very grateful.
Also, after reading
@Kiki's comment, I'm concerned/confused about the food we are giving her. Right now her food is 28% crude protein and around 1% calcium.
Is there a different food we should be giving her? I feel like every time I look into this I get a million different answers. If anyone has specific brands they recommend, or could tell me what percentages if protein and calcium I should be looking for, I'd really appreciate it.
On the calcium question - for most of her life I had oyster shells in a bowl next to her food and she seemed to peck at them occasionally. As some point I noticed that she wasn't pecking at the shells as much, and then one day she laid a shell-less egg, so out of an abundance of caution I started putting just a little bit of crushed oyster shell in with her regular food (I know that they are supposed to have a choice about when to eat the shells, but if she wasn't eating the shells at all I figured it was safer to make sure she was getting at least some calcium and not risk an egg emergency). Then, when I took her to the vet about a month or so ago, the vet told me I shouldn't be giving her oyster shells at all and that she recommended using a calcium gluconate solution in her water so that I could be sure she was getting the calcium in the requisite amounts. She said I should use the calcium gluconate when the bird was on-lay, and not give supplemental calcium when the bird was off-lay. A different vet told me to be very careful not to give too much calcium because it could cause, in his words, "total system shutdown."
What would you all recommend I do going forward with calcium, given the situation?
