3 days sometime between 11pm Sunday night and 6am Monday morning. I went ahead and pulled the first 6 babies (all hatched between day 21-22) last night and put them in the brooder (going to try and attach a photo) I left the one who hatched yesterday (day 23) afternoon as it was still wet, and we had another hatch this morning! The newbie was looking awfully sickly and weak when I left for work, but my husband says it's perked up a bit, so fingers crossed! That leaves 4 eggs unhatched at this point, no sign of a pip from any of them.
