Hello, We have one blk australorp rooster and 6 blk australorp hens plus more (20-hens total). I know the rooster can't cover all these gals. We'd like to have him fertilize the blk australorp hens and then hatch some out. I currently have a broody hen, but no fert eggs that I know of. Anyone have suggestions on how to go about this challege? They free range during the day and roost in a closed coop at night. Thanks for any help/suggestions!
