Hello! I have 3 black sex links and I just had a couple questions... They were straight run btw Two of my black sex links look completely different then the other one I have 2 have uneven wing feathers and no tail feathers where as 1 has all even wing feathers and it does have tail feathers and this one is also a lot more red then the other two the other two barely have any red. All three are aboit 3 weeks old. Is this any indication of gender? I was told by a friend that its looking like ill have two roos and one hen. Can anyone share any thoughts?
