Which one to feed your bird? Which is more nutritious? Can they be mixed together? If then on what ratio. These questions lingered long on my mind as I am in the continous quest to find the best seedmix diet for my birds and here is what I uncovered: Millets contain at least 11% protein in weight, a vital ingredient in feather prodution as feathers are mostly protein in the form of keratin. Other nutrients include various types of vitamin B, folic acid and carbohydrates. Having no gluten, millets are known to have no allergic effect. Millet, aside from the canary seed should comprise at least 30% of your seedmix. You go to a super birdstore and suddenly found a variety of colors, with a price difference t almost 50%, white, also known as "pearl" being teh cheapest.
The fact is, laboratory nutrient tests on the millet is the same to all its colored varieties, thus, it oil boils down to choice. Your birds' choice.
I have honestly given them all those four types in one mix and one color stands out: The black millet. Stands out in the sense that it is the only think left in the plate, as much as possible, cockatiels or finches, they dont want to do anything with it unless starvation moves in. Given its relatively high price, my birds are giving me a great favor. The others are consumed fairly but not until the white "pearls" have pretty much ran out.
So there you have it: Winner of the royal rumble. Nutritious, cheap, readily available and very much popular to your cockatiels, the white aka "pearl" millet.
