The first chick hatched last night about 10:00 on day 20 , second 10:15 third today around 12:00 noon. This is first hatch with my homemade incubator and I have'nt opened door since day 18 . humidity 71%- 72% , all 3 chicks hatched perfect and are doing awesome. I have had no isues with bator so temps have been 99.5-99.8 the entire now 21 days. the proublem is i am a newbie and could'nt tell by candling if the eggs were fertile , and the eggs were black maran's dark eggs. The first to hatch was a black maran. My Qestion how long to give the rest of the eggs to hatch at least 3 more have piped but no action other then egg moving a littel how long are the chicks ok in the bator wile I wait?? thanks.
