The ratio of male:female chicks born to one or two albino parents is the same as any pair - 50:50. However what you might have heard or read about is the fact that there are generally more albino/lutino females. This is simply because with any sex linked mutation, the female only requires one copy of the mutation. Females have an X and a Y chromosome, and if the father (males have XX chromosomes) is an ino, that means the ino gene is present on BOTH of his X chromosomes and if paired to a normal hen he can ONLY produce albino hens and cocks split for albino (the cock will pass one ino X chromosome to his sons, and the other normal X chromosome will come from the hen).

The reason there are less males is because of this and the fact that male inos can only be produced when the father is either ino (or split to ino) and the hen MUST be ino as she can only pass on her one X chromosome and in order for the sons to be ino they must get one ino gene from the mother AND the father.

Sorry for the long winded explanation, hope it makes sense
