Solution to newly hatched chicks playing kickball?

Normally when I hatch, I don't put the eggs in anything, and just let the newly hatched chicks run free. Of course, they kick the other eggs all over the bator. The only problem I have with this is that through the small window, it can make it difficult to keep an eye on pips. The eggs always roll into the corners. I've tried putting them in styrofoam cartons, but I'm not a fan of this method. I don't like them sitting straight up. That's just my preference. So I was thinking about using cupcake liners to hold the eggs in lockdown, maybe trimming them shorter around the top. Parchment paper is pretty sturdy. Those things are designed not to get soggy. Or I could just use the foil ones. Anyone ever tried this?
