Bantam nest box size ?

[mybackyardhobbyfarm]

How much space would a Serama need for a nest box?
I know minimum coop space for bantams is 1sq ft per bird and 4sq ft per bird for the run.
Does anyone have bantam nest boxes ? If so, what size?im looking to get Seramas so they are very small.
Im also aware that I can use buckets, baskets etc or that they will lay in a standard size nest but I’m curious on nest box size for bantams, more particularly Seramas.
TIA

I think something like 8" across, 10" tall, and 10" deep, would work.

Too big isn't a problem, just bed each box well. Too small isn't good though. I'd do 10" x12" or so; just to make them simple.
