She has found a quiet corner in the coop and is sitting on a couple of eggs I have no rooster, so they will not hatch. What is the process if I get some fertile eggs? How soon do I need to put them in? I saw some nice ones that are ready to ship in the hatching eggs section, or I could travel out to a local farm, but probably not until this weekend. Is that soon enough? Would love to get some chicks the old fashioned way!
