She is one of the higher ranking birds of the flock (and still is) so im not concerned about her getting picked on or anything. I have safeguard so I will worm her with that. She is being a bit picky and not really interested in things like scrambled eggs and oatmeal which I tried giving her. So I have been also feeding her raw eggs and mealworms. I am severely concerned about her weight since she is completely emaciated. Is there anything I could give her to help her gain weight? like calorie gels or something?
Do you have photos of her and her poop?
I understand your concern about her being underweight. She did not lose all in one day and won't gain in one day.
Again, I'd encourage her to eat her normal feed, you can offer it wet or dry.
Oatmeal really has no nutritional value for a sick bird, I'd omit that completely. Egg, fish, meat can be offered as small treats, these are extra protein and have essential vitamins and nutrients in them. Mealworms are high in fat, so only a few of those a couple of times week. You don't want her to gain fat which can cause liver and kidney issues.
Normal feed, a treat a few times a week. No "calorie gels" whatever those are.
IF she does have worms and they are contributing to her weight loss, eliminating those will go a long way in getting her healthier.
Deworm, check her for lice/mites, see that the crop is emptying. Feed her her normal feed.
Patience!
I'd encourage her to eat her normal feed, see that she's drinking well. Check to make sure her crop is emptying overnight, look her over for lice/mites and deworm.
