I have added a few chicken eggs to hatch with my turkey eggs before.Almost always works well.I want to add 15 turkey eggs to the 10 that are nine days old already in my incubator.I wonder what is the best day to do that and what about the waiting time for the new ones to heat up?Will that cool the other older ones down too much?I also wonder about humidity at lock down.How will that affect the newer ones?I have checked the first eggs and 10 of 12 are growing.I'm gonna end up with more that I can incubate.I'm not sure what to do with them.Thanks for any and all help.
