Chick up date

Sorry this isn't about hot dixie chicks-more like the kind that cluck and eat bugs out in the yard. Sunday is the big send off. Meaning I will put the eggs in the incubator. Days one through eighteen should have humidity of 50 percent-humidity gage bought with extra batteries. The trick will be keeping the humidity to just fifty percent. Temperature at 99.5-shouldn't be a problem.I think I will have sixteen eggs to put in the incubator so with a fifty percent success rate I should have eight babies. Talk about counting your chickens before the eggs hatch(sorry farm humor). Wish me luck. I have two roosters, three hens,  two turkeys, and two ducks  right now. I'd like to have at least six hens.
