Yes she probably will unfortunately. How are you force feeding her? Have you ever heard of torpedoes? That really helped me get even more nutrients into a sick bird, along with tube feeding. Since she is under a vet's care, I would probably ask them about teaching you to tube feed and if torpedoes would be ok. Since she is drinking on her own, torpedoes (maybe save tube feeding as an idea if torpedoes don't work) will probably work well.Here it is mid afternoon, and so far has drunk a fair amount of water on her own, but she hasn't pooped since this morning and her crop is not emptying...
It's probably not fair to her to keep force-feeding her for an extended period... she really hates it... but if I stop I think she'd just waste away and die...
