Okay, so I hatched a good bit of our eggs trying to replace my ladies after dog-pocalyse (I was only left with 4 hens, 2 of which were meat birds). I have two different roosters, not related, and they both sired pretty equally. But I'll be blowed, d**n near 75% of all four hens' hatches were cockerels! What in the world is in their DNA that caused them to put out so many boys?!
