I just had 8 out of 20 duck eggs die during lockdown. They were fine 3 days ago when I moved them from incubator to hatcher. Hatcher is an incubator set at 97ish with 90ish humidity. I did open it to spray them a few times, maybe too much? One starting coming out then died but the others seem fully developed (at least as far as I can tell by candling) but dead before they pipped. Help!
