I've been reading everything I can on this site, just registered and I have my first question! I am the first time owner of 20 chicks, they're an assortment, 2 & 3 weeks old . I'm really enjoying them. I'm loving the "detective" work part of figuring out the Roo's. I definitely have my suspicions on some of my "pullets". Some of the breeds are easy to see a difference already, for instance I know that one of my three Columbian/Rock crosses is a Roo. I'm puzzled by the Barred Rocks. I have four, two are much more feathered than the other two, all have similarly dark legs and head spots. Is it necessarily true that pullets will feather more quickly than Roo's? or are there variations in feathering among the same age & sex. Thanks for any input.
