There are 4 from the same brood. One is very underdeveloped compared to the others. I have read everything I can, but still cannot get a decent guess on these guys. The comb on this one is still dark. Bird 1 This one still has nubs for tail feathers. Bird 2 This is the biggest of the four, but has a fairly red comb and wattles starting. Bird 3 This one also is turning red in the comb and wattles. Bird 4 Bird 3 on left and 4 on right. Any suggestions? I'm afraid these are going to turn out to be all boys! Will I be able to tell on this breed more by the hackle feathers or tails first?
