I'll try to make some suggestions:
I also put avicalm on the parrotlets food since Gemma is so hormonal.
You could reduce the protein food, that will make her less hormonal.
Further too much protein isn't healthy for the kidneys.
and now egg food has been incorporated.
Please feed that only once a week.
Pellets: Roudybush in a separate container that is barely touched. EBs dont eat it at all. I do put it in bird bread tho.
If the birds absolutely don't like them just leave them out. Your bird diet is so rich and full of nutrition, they don't need them.
The pellets' vitamins won't work in bird bread, because heat damages them.
Sprouts: I offer sprouted seed for at least 2 solid weeks out of every month spread out with batches. I mix a sprout mix with legumes with a lady gouldian mix and sprout that.
A high quality sprout mix twice a week is enough, sprouts are very rich of protein.
Supplements: calcium in water once or twice a week, acv in water once or twice a week, probiotics and vitamins sprinkled on sprouts once or twice a week. Liquid kelp for water once or twice a week (iodine specifically for budgies prevent tumor growth).
I offer a cuttlebone, they use it when they need calcium, I wouldn't sprinkle it over the food.
And I think when you feed Harrison's lifetime mash you don't need further vitamin supplements. Please don't overdose vitamins.
