Let me give you a quick background. Short story. My friend, Lana and I always wanted chickens. I have a coop in my yard (prior owners) and Lana lives 1 mile away. On a whim, we decide that we're finally getting chickens. We have 12 and they are 3 weeks old today. Like a proud Mumma, we have: Big Bertha, Mr. Schneider, Cupcake, Mase, Rosie, Brownie, Ice Cream, Gladys, Mabel, Stella, NitWit and one un named still. Not sure if we have a rooster yet or not. I have a ? and I am embarrassed to even put it in print b/c it's so ridiculous. How do you know if an egg is fertilized? I expect we'll get a lot of eggs eventually and if we do have a rooster how will we know? I am reading books left & right & honestly, cannot find the answer to this ?.
