I'm sharing a chick order with a neighbor (still a small order, 7 birds total). As part of the mix, she is getting a BR and I am getting a Dominique. Any tips on telling these chicks apart? I know that the BR has a single comb and the Dominique a rose comb. Will we be able to tell those tiny combs apart at 1 day old? They will both be pullets (we hope!). Thanks!
