Columbian Plymouth Rock standards

[Yard full o' rocks]

How do I go about obtaining the "standards" for Columbian Plymouth Rocks? I am currently growing up a flock and would like to know what to keep (and why) and what to cull.

THANKS

you can search online for columbian plymouth rocks and there is a wealth on standard info from th 1930 and 1940s. Its basically an online poultry library that you an access. I think if you go on the plymouth rock breeders club website you can find the standard from back then and take a look at it.
