Well, we have 4 chics and they all seem to be ok so far. This is day 21 and of the 13, 4 have hatched. One of the chics had a gross yellow/white mass hanging from its butt area...I'm guessing part of the yolk not yet absorbed. What worried me more than that was these little green balls (like caviar) also coming from the same area. What gives? Did my baby hatch too early, will s/he survive?
