That's because the other birds are also laying there.We just looked while she was off the nest and she has 17 eggs on the nest!!! OMG!!! Not sure where to put her.
Has she been on the nest day and night?
Candling the eggs would be good.
Mark the viable eggs and remove any others daily.
Moving her is a crap shoot, she may stay or not.
Best to set up a nest in the coop that is fenced off from the flock.
with space for feed, water and to poop.
Move her and the eggs well after dark.
