Putting all my eggs in one basket

I ordered a new incubator weeks ago, and I'm so excited to have finally received it! Its fully automatic, and can hold up to 48 eggs. I fired it up, and put a dozen eggs in to test it before I order rare breed eggs. Right now I put in, 3 Houdan eggs, 1 welsummer egg, 2 EE eggs and 6 Ameraucana eggs however, since I keep my birds as a mixed flock, there is no guarantee what mixes I will get. Its not spring without baby chicks, so for me, this proves it...Spring is finally here!!
