we have 2 and the chickens haven't ever used them. maybe taking away the other nestboxes would make it less of a choice for them though. we also have a tunnel between 2 chicken houses so the hens can go to the 2nd house (without a door) to lay the eggs. that way it takes longer for other animals to get to the eggs, and the hens really like the extra privacy.
