? about my chicks hatching early

[ChickenMan08]

My RIR chicks have all hatched today

And are all fine. But my ? is that they hatched on day 20 is this something to worry over or not? I will post pics of the new chicks soon, but go ahead and check out my page now for pics of my other chickens. Thanks

Nothing to worry about, sometimes they will hatch anywhere from day 20 to 22.
