My Cayuga eggs just showed up, they are sitting on the counter chillin. So, I am looking for a duck incubation guide, but can't find one on the forum through search, does anyone have a link handy?
Here are a couple of links. One is actually for hatching goose eggs but I feel it has very good info for hatching waterfowl in general. Hope this helps!
Goose Incubation & Hatching Guide - Completed!!!!
Incubating and Hatching Duck Eggs

. Mine pretty consistently take 17 days to hatch. Haven't decided whether to pick out the biggest eggs from our jumbo girls or to get a some from a breeder for “new blood”.

I love a challenge!
