I am wondering what the 2 White ones are. One is pure white and the other is a White/Blueish color. They are the same exact size as the 2 mallards. They are WAY smaller than the Cayugas. Quackers is the white one, which I thought he was white pekin. Well, he turned 1 this year and he is a boy. The blueish/whiteish one is a female. Let me know what you think.
