will chickens lay on bare wood?

I've built some roll away nest boxes, and with the astroturf in there, the eggs dont roll very well. if you kinda mess with the eggs as, per se, a chicken moving around might bump them, it will roll away, but not as I expected them to do. Will the chickens lay on bare wood, or do they need something soft under their feather butts to incite laying?

The boxes have about a 3 inch drop per 20 inches.

Thanks ahead of time!

While I use sawdust in my nest boxes, I have had hens lay eggs in a bare box. But most of them seem to prefer the boxes with bedding. Bedding is a relative term though. I've had hens like a wicker basket, a soft lounge chair, the cat's bed, and even under a bush on the bare dirt.

My chickens are currently favoring the ground under a bush rather than the nesting box with wood shavings in it. Go figure.

Mine will.

No matter how much pine straw I put in the nest box, they always move it around until there is bare plywood to lay the egg on.
