I am hatching my first Muscovy duck eggs. I have heard they are hard to incubate and hatch out, so I am concerned. On the first day of lockdown, one hatched, another pipped, (it hatched the next day) and there has been no other action. How long do I leave them in there? Can I do the same things I do with chicken eggs? (Floating, candling, assuming they quit?) Or is it normal for a hatch to stretch over days? I use a Brinsea OVA 380. I sprayed them twice a day and kept the humidity at 30% until lockdown. Help would be very appreciated.
