Does it matter the age of the hen when is best to incubate eggs? Is a younger hen more likely to have better clutches hatch out than older ones? Is there a minimum age a hen should be before her eggs are incubated? I have a young pullet who started out early, like 5 month inthe middle of winter, laying a HUGE brown egg daily. I was expecting "first eggs" to be on the small side, but hers have always been jumbo. Will they get bigger as she ages? She is a black sex link. Is there any chance her egglaying will be inherited if I hatch out chicks from those eggs? I also have some red-x hens who lay a large egg but not nearly as big as hers, and they are the same age.
