I set 42, 4 were infertile, 1 quit. As of this morning 33 have hatched. The 4 eggs left have not peeped. I love baby chicks! There are buffs, RIs and BR's. They are so cute, but 33 is a lot. I have them in the house, but it is plenty warm enough outside without heat during the day. Does anyone move babies that little outside? I have a nice shed that is secure, but worried about over night temps. It has been 90's during the day, 70 in the am. Do you use a heat lamp at night?
