Is there a way to "test" whether or not these eggs would be any good? The hens only started laying in late November. I don't THINK they STARTED laying where I found these eggs and there's easily 12 of them. I only have hens, no roos--so it's not like they're fertilized and might have chicks or anything. HELP!!! Dh wants to toss them! I'm figuring if they float in water, they're out. Or if I open them and the yolks don't "stand" up then they're gonners?
