Hello. Yes, most definitely you need to worry. I can try to help you but I'll need some more information to be able to give you my best advice.
Are you postitive it is a female bird?
Is she a lone bird or does she have any cage mates?
If she is hand tame, can you have her step on to your hand or finger, raise her to eye level and look down along her underneath. Tell me if you see any indication of a lump or swelling on her lower tummy.
If she is not hand tame, don't stress her by trying to handle her. Just do your best to make the observation with her in her cage.
I need to know all about her usual diet and, does she have a cuttle bone in her cage, and does she have access to any kind of grit or gravel?

If she is definitely female, and considering the posture you are describing, I don't think we can rule out the possibility of her being egg bound either. If there is that visible swelling, that pretty well guarantees the problem but the absence of it, visually, does not rule out the possibility. The diet she has been on makes her very at risk of egg binding also. A proper diet would not be more than about 30% seeds and seed products. Seeds are very high in fat, some worse than others. They need a seed mix that has no sunflower seeds in it, (way too much fat) and they need a good brand of pellets mixed with the seeds. But also, in a separate dish, everyday, they need lots of fresh fruits, veggies, leafy greens and a lot more. If she has had only seeds and if she has not had the cuttle bone as a valuable back up source of calcium, she could be egg bound. That is a life threatening situation, all by itself. But it can get much worse if left untreated. She will be at risk of having the egg rupture inside of her, which is why I said if you handle her, do it with the utmost care. If that happens she is at risk of massive infection. If she strains too hard, trying to pass the egg, she can suffer a prolapse of her uterus. She will literally turn herself inside out. If that should happen, you have a very short time to get her in the hands of a competent vet to save her life. The posture you have described, while not the only possible explanation, is very indicative of a bird who is egg bound and straining. I'm sure you understand there is no way I can diagnose for you from long distance, and I'm going to urge you to get her to a proper vet just as soon as you can. In case you don't already have one you trust with birds, I have some links that should help with that. Pretty much all Avian vets have, at the least, someone on call, 24/7. It's just the nature of birds for it to be an emergency much more often that it's a regular office visit. Usually all we have to do is give them a call, tell them what we think is going on and they meet us there if it's after hours. On the chance that an egg is her problem, there is one thing you can try. Take her, cage and all if possible, to a small, hot, steamy bathroom. If you can do it without stressing her and without putting any pressure whatsoever on her body, you can scrub your hands, then with a clean finger tip, rub some cooking oil around her vent. The combination may help her pass the egg. However, this is a last ditch, home grown attempt and doesn't have a very high success rate. It's only better than nothing. If she is bound up and if she doesn't pass the egg after about 30 minutes or so of the steamy enviornment, then she needs to get to a vet asap. I hope this helps her out but if you have any more questions don't hesitate to let me know. I'll be here, off and on, for the rest of the evening, EST. I'll sure do everything I can to try to help the little sweety. Patricia
