Laker prefers seeds but really enjoys
bread [flat breads & whole grain breads],
fresh carrot tops = but only after about 5 days of offering them to him every day & running away from them the first few days in a blind panic - so frightened of greens!
Rio is game for just about everything
so i really should try harder.
Once one of them tries something the other one has to check it out. So in a way
having 2 Budgies can be a good strategy. Rio was very 'game' to try the noodles, once he saw Laker's excitement.

Laker learned to eat noodles by being curious as i ate my lunch - not always with him in my meal but with him in his cage on the dining room table & offering samples thru the bars.
In the spring you really should try & find some nice green seed heads for them - find a steady supply at a park or grow your own if you can - your neighbours will probably think you're mad, growing grasses & millet. In the category of greens - i recommend
sprouts - all kinds - my guys are very fond of
broccoli & pea sprouts. I think you are all aware of my threads on that experience.
I don't cook like Sarah etc - i have tried but am not consistent - so
my style is to offer what's going that is Budgie friendly or fresh greens. When i make apple pie or something they get fruit strips or pie to try [pastry is a big hit & I make mine with Whole Spelt, Refined Spelt & a dash of Pastry flour & lard]. They get this rarely. If i make
pasta & veggies they get some - usually around lunch or dinner. So far they haven't gotten into
Rice - can't say why.
I have to confess that some days they get mostly seed with a fruit pellet mix on top. I put no more than 2 tbsp [probably less] in each of their dishes & they get a 1" to 2" millet sprig each at night or if we're training [my husband will sneak more to them if he's around]
