yes there is a big defference between all the line in Oz ,because they come different origine .Do you notice a difference in the 2 lines?
the last import marans from the UK most of them are English type .clean legs ,not all .and they are taller on they feet , .some of them don t lay dark eggs .
they cross well with a old french lines . they produce what cull hybrid vigor .bigger birds . most of my BC / BLC / Splash and cuckoo are 50% OZ line and 50% import line .
I do have all sort of line in my farm .old and new import .
for me the standard is a same breeding to the old frensh style marans what the SOP call for . balanced farm hen no extreme .
