I'm using the Nurture Right 360 to hatch duck eggs. Today is day 28 of incubation, aka, their due date. On day 26 we had 2 early Pekin hatches, they are brooding right now. I have 5 more eggs in the incubator, they are all inactive, I cant hear tap backs, chirping or anything. I have 4 khaki Campbells and 1 Pekin in the Bator. What should I do? Just wait? Thanks in advance, Immi!
