Sugar is perfectly fine, she wasn't the one vomiting seeds, that was Wheatley. And I took him to the avian vet and he checked his weight and everything and he said that everything was fine. I told him how I have the budgies a treat stick on Thursdays, and how that was the day Wheatley would vomit, he told me to lessen how often I give them a treat stick and to come back if he continues. I didn't give him a great stick yesterday like i normally would, and no vomiting

I'll keep and eye on him, see if he starts again but so far he's doing great. I never used to give them a treat stick that often, but they were having a sale so I bought quite a few.
