Dark Yellow Cockatiel is it Primrose???
I got these three birds from a friend not sure of the genetics, he said they are from the same clutch and parents are pied and have the same dark yellow color,
So far i think they are females, as non of them is whistling or doing the wing display, unfortunately none of them have any markings under the wing or tail feathers,
Anyway, i just want to develop this color, so what is it and how can i breed more of it,
Any advice or suggestions are appreciated, as i think the yellow would look cool on a yellow cheek bird
