Answer 1

Only a qualified vet is able to s*x many birds. This usually is an expensive service.

Answer 2

The male Umbrella cockatoo usually has a broader head and a bigger beak than the female. During their puberty the female Umbrella cockatoo can begin to develop a more reddish iris than the male.
