Incubating Duck Eggs

[Hammertime]

Hey Guys,

Hopefully you guys can help me out. This is my first time incubating eggs, and I don’t want to screw this up. These duck eggs should be hatching tomorrow sometime. I’ve noticed that these eggs are getting “bruises” with dark spots. Is that normal or should I be concerned?

I’ve been reading articles but I still feel like I’m confused on pipping snd zipping. I want to make sure I’m doing everything right, because these are eggs for one of the biology classes I teach.

Any help would definitely be appreciated.

Also the sponges are to increase the humidity level.

I've only incubated duck eggs once, but the bruising you're seeing is normal, meaning they are soon to hatch.

If any of those were rotting, you'd have smelled it already, trust me.

Pipping is when they break through either internally (where the bruising most likely is) or externally where you first see a crack, then a hole.

Zipping is when they peck at and work their way around the inside of the egg and it kind of looks like a zipper from the outside.

Your humidity should be up around 60% - 70% or so.

Thank you so much!! Your info helped a lot! Just hoping for some healthy baby ducks! I live in a super dry air area so keeping the humidity up has been a challenge.
