W4w I set an assortment of olive eggers, blue ameraucana, buff Orpington, and a couple of ccl. I was very nervous to put the eggs in. It was like no turning back if something awful happens with my temps! But they haven't move from 99 to 100. Well since I haven't had my chickens start laying yet except for one ee that I bought already laying I'd have to say waiting to hatch is more on the nerves lol.
