if my "hatching" box is not ready by a week this coming saturday, I am going to create a wire/mesh "box" that will fit in the top hatching tray.
There is the most clearance on that tray (about the same space and clearance as the hatching area in the bottom)
I am using mesh so I can see what is going on without having to open the door while chicks are pipping.
Too bad you are not closer, i have 8 quail trays i doubt i will use.
What breeds are you hatching this time?
