Hopefully not. As long as mama keeps the humidity up by sitting on them. It can be a few more days so try not to panic. Mamas know what they are doing. My Muscovy are alot smarter than me.

Whatss the breed of mama duck? All domestics take an average of 28 days, Muscovy 35-37. Ducklings take a long time to hatch once pipped internally best thing to do is to wait patiently.
