You may have just worded it incorrectly, and meant something different, but; a hen with one copy of the blue egg gene is definately going to lay blue or green eggs................................ when crossed to a roo not carrying a copy of the blue egg gene, on average, only half of her pullets will lay blue/green
That would be true if the hen or rooster (or both) were homozygous for Pea comb. But if the hen is heterozygous for pea comb and the rooster is single combed, one quarter of the female offspring will lay blue/green eggs.
