I have Bourke's Parrots.......they are of the Neophemas variety. A grass parrot. I know none of the seeds mentioned. My birds breed freely, and I have always found good homes for them. I have trouble in preventing them from breeding. I don't like to feel the female will get worn out, as it is not in the laying of the eggs, but the raising of the young that is the hard work. They don't breed in Winter. But will do so from October to April ( here in the warmer months)
Feeding them is the same as tiels...in Winter you must change their diet to a more oily seed, like adding linseed and black sunflower seed to enable them to put on fat to keep warm. In Summer you cut those two out, but feed a little of the light coloured sunflower seed in their mix. Summer I give a little greens, but grow my own wild grass seed and give it to them fresh.
You own a bird, love it, and take the time to do a little research on what they would live on in the wild.............believe me, it will make the world of difference to you feathered friend.
