Thank goodness you found your dutchie hen! That must have been so upsetting. Do you free range your chickens? or did your hen escape somehow?
My Olive egg from Myrtle isn't alone in an incubator. I don't even own an incubator. My silkie is sitting on a clutch, a mix of her own eggs, one or 2 from her daughter pullet, and a couple of standard size mixed breed eggs. I am worried about the olive egg because Mima (hen) would have to keep it warm a few days after her others hatch.
I checked a bit earlier and nothing's up yet. I usually can't wait to see pips and hear chicks but the later these go, within safety of course, the better it could be for the olive egg to catch up.
I hope your lone egg hatches too!
