I have 8 buff Orpington hens. Our city does not allow roosters. My questions are. Can I get a rooster off craigslist or borrow one from someone. And just keep it locked inside the hen house with the hens for 2 days? Then I would return the rooster or stew him. And how long will the eggs be fertile after mating assuming he mates some of the hens?? Also are the eggs fertile 2 days after mating??? Thanks for your help
