Budgie seed is basically millet, canary grass seed and oats groats, which a lot of birds love.
Nutriberries vary by the variety but most contain hulled millet and canary grass seed plus oats groats, cracked corn, sunflower meats, safflower seed, peanuts (some have dried fruits), canola oil, soybean meal, wheat flour, ground rice, and binders like corn syrup, glycerin and maltodextrin. Plus added vitamins and minerals.
The binder is how the added nutrients get consumed. The fact that all these seeds are hulled allows the binder to get swallowed instead of discarded when the bird hulls the seeds.
So, are budgie seeds too small for a CAG? Nope! The seeds look tiny to us big two legged silly creatures but to a CAG they're little bite sized morsels. They can easily hull the seeds and swallow the good part.
Hi, Quasar! Lookin good!
