This was written by Curtis Hale and is on the MOAC website. Excellent information.
Some of my tips that I have collected over the years are:
1) a high tail on a cockerel can see improvements in his sons if the hens has a low tail.
2) if you want larger hens breeding a your largest cockerel to average sized hens won't work and will produce average sized hens, but breeding your largest hen will make for larger hens (even if not breed to your largest cockerel).
3) In a pairing it is more important that the cockerel's color be perfect than for the hen's color to be perfect
4) in a pairing it is more important for a hen's type to be perfect than for a cockerel's type to be perfect
5) combs tend to be passed from the hen in a pairing
6) A short shanked hen and a long shanked cockerel produce correct proportions while two short shanked birds will
have offspring that are dumpy and two long shanked birds will have offspring that are too lanky and upright (even if
the parent are with in what is acceptable just on the bottom or top of the spectrum)
7) White under coats on the BCM can be carried by the hen, but only show up in the cockerel
8) Dark Egg color can be restored successful in a line that has lost it with use of either a cockerel or a hen (both
carry all the genes).
Well that is a start for discussion. The best thing really to do is to pedigree your flock and keep good notes. Your
Marans may be built on a different portion of the available gene pool than someone else's flock and what they find in
their flock may not hold true for your flock.
