I ordered a few Golden Campine chickens from Ideal Hatchery and, through a course of events, have ended up with three rooster chicks and one pullet. I will choose the one roo that I want and have alternative plans for the others when they become a bit older. My question, though, is when pullet eggs become hatching-type eggs? (I know that daddy Roo has a bit to do with it, but . . .) My plan, because I know that GCs are not really broody birds, is to gather a few eggs and either put them in the incubator or under a broody hen of another breed. Is this something that might work to increase my paltry GC flock and, if so, how long should I wait before trying to hatch this poor overworked pullet/hen's eggs?
