I am getting ready to set 24 eggs in my new Brinsea......I'm soooooo excited, I can hardly wait! This is my very first attempt at hatching eggs. Anyway, when I candle at 7 days and throw out the non-progressing eggs, is it possible to put new eggs in to replace the ones I took out? I recognize there will be a one week difference in the time they hatch, but can it be done successfully? Has anyone done this? Will upping the humidity on day 18 for the first batch "drown" the second batch? Is this my "reason" to get a second Brinsea?
