I have read that egg laying ability is inherited from the rooster rather than the hen. Of course how you know how many eggs a rooster can lay is a mystery to me![]()
Seriously though, I read in one of the old, old books about breeding and layers that the rooster's line is the one the egg laying ability comes from.
so you hatch eggs from the best layers, and keep the cockerels to breed from. i'd say keep the pullets too, and if you can deal with inbreeding some in the line, put that cockerel over his mother and sisters. and any other hens that are quality layers too i'd say.
rooster lines may influence laying, but the hen's line influences size and type much more. (typically, not always tho)
My thought exactly on keeping the cockerels, etc. Plus I can say from experience in addition to reading that hen influences type and size. Does tend to muddy the waters though.
