I read something very similar to how you just described Norway in the American SOP. It says the Marans hen should have the character of a rustic farm hen, giving an impression of solidarity and strength without being too course. Norway is pure gold if she throws big meaty offspring. The birds we butchered over the summer all had puny breasts. I definitely plan to work on that.
it is very important trait when we work with a marans .
body type /mass and body carriage will score around 70 point between them at the show more than any point .
Plus the most important thing of them all. THE DARK EGG
for me those trait are first .
the rest .tuning the breed is later , comb ,eye, parasitic white ,tail angle etc...... .they only score you 5 to 10 point at they best or less . END those quality don t pay the feed and the rent . Mass and Dark egg do.
