I have five BLRW pullets that I got at the same time. Theywere all supposed to be five weeks old two are big, one a bit smaller, one a bit smaller than her and one that is literally half the size of the biggest. The teeny one is second from the end on the rigt in the roosting photo on my BYC page. I know she's not a bantam - breeder onlt raises BLRW and Copper Marans.
