I paired a non-crested hen with a small crested cockerel. About 50% of their offpsring were crested. Most were small crested, but I have one with a medium crest and good type that is now 13 months old that I am currently collecting eggs from.
So...the original cockerel that the non-cressted pullet was paired to only had one cresting gene. To carry this breeding line forward I have mated the 13 month old hen with the guy below (don't pay any attention to his color. I am focusing on big crests and straight combs with this pairing).
Oh... I also pair a medium crested hen to the same small crested cockerel as the non-crested hen was paired with. 100% of her offspring were crested.
Good to hear the ratios in your results. Can't wait until you get true cream into this guys line- he has awesome type!
