Okay, so it's only our second set. But, hey! It is our largest. We just set 46 eggs in our bator and 2 under a broody hen. And, boy, what a mix we got going, too! BCM, OE, Barnies, Silkies, Bantam EE, Sebrights, Porcelain D'uccles, EE, and a couple of mystery eggs. Plus, I am in the process of building a new brooder. 24Hx24Wx58L and a foot off the ground. It will be done tomorrow when I get home from work, even if I have to use a flashlight! Not going to wait till the last minute and throw a brooder together. Not with a set this large.
