Sorry, that your chicks didn't make it but did you dip and incubate or did you dip, rinse and incubate? Also, did you dry before incubating or put them damp into the incubator? Oh, and did you heat the acv or just room temp? Are you going to try again?
Room temperature and then let them air dry before putting in the incubator. Yes as soon as I get an egg turner. I am terrible at remembering to turn the eggs. I believe that the eggs that didn't develop (before temp spikes and outages) didn't get enough turning.
