Hi,
After reviewing the video & picture you sent, I think you have 2 males. The Grey bird is definitely a male – he is a normal grey male. The other bird is not an albino, it is a Lutino cockatiel and appears to be a male. Check the underneath side of the long wing feathers, and if it is a female, there will be yellow spots. But the behavior and vocalizing is more like what a male would do. If you still decide to get females for breeding, both the male and female should be at least 2 years old before you put them together for breeding. And you can only have one pair of birds in a cage for breeding.
Thank you for asking Lafeber,
Brenda
