This inccy is a waste of time really, I understand what you mean, lean the eggs against eachother, it gets worse the more mature the eggs become as the chicks/ducks or what ever are moving and i swear they roll themsleves about. Only thing i can warn you is, make sure any eggs in the center directly underneath the bulb ensure you move them out and change them as i had one particular duck egg pip early, and it eventually died. Recommendation would be to get a diff inccy, which i know isnt always possible, I find my novital handy as an indivindual brooder for sick ducklings! And no, these inccys dont have dividers! Egh! Bit of a rip off really!
