I have 3 roosters. Pretty sure a fourth (a silkie) but so far not a trouble maker like the others. 2 are california grays and one is possible a black sex like rooster (he was supposed to be a barred rock pullet). All my chickens are 3 1/2 to 4 months old. The cockerels were an oopsie They won't be with us much longer either rehoming or ending up in the freezer. So my question since all my girls are 3.5-4 months old and the boys are trying to mate. Are they possible going to have fertilized eggs when they start laying? I've been told that mid July I may see eggs. I've also read that hens could still lay fertilized eggs a month after getting rid of a rooster. Does that apply to younger ones or just adults. Also since the boys are driving my girls nuts should I push my Husband to cull them sooner rather then later? I don't want them hurt by frisky teenage boys.
