I have a couple chicks i believe both to be roosters still really hoping there not. The only real distinguishing factor in the 2 is one has a real dark bright comb and waddle is well showing at 6 weeks. The other the exact same age has a fairly large comb awell but its very pale and waddle is a little smaller. I believe there d'Uccle but were crossed somewhere a few years back in the bloodline. Im just wondering what anyone elses experince is with light combed birds do they turn out to be roosters later or vice versa.
