How can I tell if my Cochin is standard or Bantam size.....

[LindsaySinai]

or do I just have to wait to see how big they are as hens?? They seem pretty small for their age and are way smaller then my mutts were at the same age. I just put them in with the mutts who are 3 weeks older(pretty sure this arrangement wont last, they're huddled in a corner with their faces buried) and the mutts seem 4 times the size.

If they're smaller than mutts of the same age, then I'd say they're bantams. My stanndard cochins are easily my biggest birds!
