I have a yellow faced hen and a yellow faced male (budgies) that bonded and produced a clutch of five. All of the babies are growing wonderfully, but to our surprise one of them came out white faced. Infact, he's the smitten image of another male in the flock. We're surprised because we have never seen any behavior from the white face male and yellow hen that would lead us to believe they mated. Throughout the entire care of the babies the two yellow faces have done all the work. These two are obviously bonded. But, there's a white faced baby! Is our hen a tramp? Can a hen have a mixed clutch from two or more different males?

Yellowface to yellowface will give you double factor yellowfaces. A double factor yellowface is a white faced bird. A double factor yellowface when it breeds will produce a clutch of all yellowface babies.

Have 400 show budgies

Yes, they can be fertilised by more than one male i believe. However, with the explanation above, i think it sounds like she is NOT a tramp ( :P )

We have had a recessive pied yellow male and normal blue hen produce: 3 normal blues, 1 recessive pied white, and a normal green before, its kinda a mix and match sometimes!
