Oh, my, I'm in the same boat! I have mine so that it separates the Ovation into 12 slots (I like to track exactly who comes out of which egg). My first to hatch is trying to give me an ulcer by playing leapfrog over top of my hardware cloth partitions!

He's currently chilling in one of the corners where I have a heat sink, and there's not a lot of space for him to climb anymore. He's not being smooshed or anything, so I say he's fine there. Meanwhile, second to hatch keeps putting her head over the top and trying to hang herself.

Gonna have to rethink my design for the next hatch in there!
