I have 5 eggs in a Little Giant Still Air incubator at day 17. I have candled on and off... Tonight, 2 of them looked really viable (veins, etc.), 2 looked questionable (their "dark mass" was about half the size of the others and seemed more "fluid"?) The last one, a Black Copper Maran egg, looked clear but had a definite air pocket. One seemed to have a blood ring a day or two ago but I can't find one now. I am leaving town in the morning and my husband is going to take over for lockdown and hatch day. I hate to toss the questionable eggs if there might be *life* in them- is there any harm leaving them in "just in case"? None of them smell bad...
