I am being told so many things about sex of silver laced orpingtons. I think I have 2 Roos and 5 hens if I am correct! Please help they are 7 weeks! I think number 1 hen, number 2/3 roos and number 4 a hen????? Their feathering is so different in the two! I think the two Roos have less black, less feathers and smaller birds ! Some have heavy feathers and really red combs. Help please!
