I have 2 different sets of serama eggs in my incubating hova bator at 45-50% humidity and 99-100°. My first batch of eggs at 14 days seem to be right on or a little behind on evaporation. These will be moving to the hatcher incubator on Monday. These also happen to be Franks eggs, great fertility rates, seemed to ship very well The second batch is right at 10 days and seem to be a little dry, the air cells seem to be much larger than they should be at this time - approx. the size of 14-18 day old eggs from the reference books that I have. These eggs are from another source and did spend a lot more time in the mail in huge differences in temperatures. I am a little concerned with their rapid humidity loss. Wonder if they were dry from shipping? I was thinking maybe I should move the 1st batch to the hatcher early and hand turn while increasing the humidity in the incubator with the second batch? Could I slow the evaporation rate of the dryer eggs this way or am I just asking for problems with the hatch (drowning chicks)? This is the first time I have tried to hatch 2 different sets of eggs with different set/hatch days. I was shooting for all of these going in at the same time but the postal service this time of year, do I need to say more? Any input would be great, thanks.
