Incubator Trays

[rwwjsw]

I am building a cabinet style incubator I am thinking about just getting a bunch of the fiber or paper egg trays to use in it I will sit them in a frame that has rat wire in the bottom when the eggs are ready to hatch I can just remove the tray trash it lay some paper towels over the wire and let them hatch. My question is has any one used the paper/fiber trays for incubating do they hold up with the humidity that is required in the incubator.
Thanks for any help
