The base of this is a regular GQF tray. The insert is from hardware cloth that was a tray for LARGE (emu/ostrich) eggs that came with my 20 year old incubator. I cut gutter screen and made "hoop house" enclosures with a "fence" at the end so they won't pop out and get behind the tray. The berry boxes are moveable for the smaller batches of eggs like the single/double you see. The only thing that's a hassle is getting some chicks out...it cannot be done quickly as the screen tucks into the wire "half fence" of the tray. I like the plastic box idea and when I have an actual hatcher (I hatch in my incubator now) that may work out well.
As to keeping the breeds separate by looks...forget about it! With the black and blue coppers, I need to keep the BCM chicks separate from the blacks of blue breeding. If hatching any crosses with other breeds, the black takes over and they all blur into visual similarity.
