Is it really 21 days exactly?

When we incubate eggs we usually have some come out before 21 days, I think the earliest was on like the 18'th or 19'th day, a lot that come out on day 21, but very few that make it after that.

So my guess would be 21 days is what's usual/ the latest day they come out for the most part (at least in my experiences).

Edit: Our avatars look a little alike

 

I've had them hatch from 19-23 days.

 

As long as you are having a good hatch don't mess with it. It does sound like you are running a little warm but that's better than cool.

 

I've had chicks hatch on day 25!! I've never had an early one or even a batch on time---wierd I know but I always say give them a few extra days--you never know!!!

 

It sound like you need to raise your temperature. You should always adjust you incubator until the egg are finished hatching on the 21 st day because that's when they are supposed to hatch.
