My 2 Black Copper Marans roos are 18 weeks old. The BC pullets haven't laid yet but half are getting really red combs, so I know it will be soon. I have some EE's that are 8 or so months old. I am getting excited to hatch some of my own eggs for olive eggers. When can I expect to see my roos start mating? Both my roos have started crowing more and in the past week their combs and wattles have turned fire engine red. I thought they were red before but now, wow, they are stunning. Does this mean they are maturing and getting real close to breeding age?
