I have two roosters both are 20 weeks old, one barred rock and one white with a patch of brown on his wings (mixed?). Well anyway, I plan on incubating eggs this Spring. I do have 12 week old 2 SLW and 2GLW that get along with the roos. The roosters are scared of the 2 year old hen. Am I right not to expect fertile eggs from her or will the roosters man up (sorry guys) and fertilize her eggs?
