I have a broody hen in everyones favorite nesting box, tried moving her didn't work so she is going to have to stick it out. My question is other hens keep laying in there is it ok to push her off once a day until day 18 and remove the new eggs? I marked the eggs I put under her.
With all the other hens trying to lay their eggs in her nest box the eggs under her may break. But yes, it is OK to take her off the nest for very short times.
I wouldn't take her off the nest, just reach under her and get the eggs. Or lift her a little so you can see which ones to grab. Sometimes a broody will abandon her nest if she's bothered too much.
Its takes longer then 18 days,about 25 days,and it would be fine. A method I use(only if you don't even want her sitting,)is,stick her plucked belly in water,then she realizes shehas not heat,and cant keep the eggs warm.
