So adorable 

I’m glad his feet did it themselves
Many advise working on them right away and I like to wait 24 hours to let them stretch out
Baby may try to eat a tiny bit in first 24 but some don’t
Usually by 48 hours they should be eating and drinking
Hatching under mom they don’t see food or water for up to 48 hours as mom won’t leave the nest till her eggs hatch or 48 has gone by
The yolk will keep them full
Did you check his butt to make sure it’s clear of any poo or goo that comes from the egg ?
Baby shouldn’t get any treats outside of either starter duck feed or starter non medicated chicken feed until they are big enough to eat chick grit. It’s important as they need it to digest other foods
