"natural" inbreeding?

Hi everybody,

I use to keep my young birds together in a big aviary till 2-3 years old. They can choose to pair with anyone of the birds in the aviary but I have noticed that they get in pairs type brother-sister more usually than with unrelated birds.

Has anybody noticed anything similar?
