Well after attempting to take several pictures of the new Budgie's cere, I've decided it is a male. In every picture the cere looks very blue; I guess he is just taking longer to turn that deeper blue than my others have in the past. It is part English Budgie, don't know if that has something to do with it.

But anyway, that takes away my worries of breeding issues! Thank you for all your helpful information, it will be useful if I ever decide to get breeding pairs. =)
