Yes. This.Mine aren't bothered either. But if it were my first broody hen, and the only one I'm likely to have, and I bought eggs for her and it's her first full setting--well, I certainly would be avoiding disturbing her.
I found the nest got dirty every few days because eggs were broken in the nest. Even though they won’t develop, it’s best to not let the nest grow. Some of my incubating eggs didn’t fit under the hen and they were left cold.
Disturbing my broody got her broken but this was the first time I let the hen sit on the eggs in the coop.
I think it’s best to move the hen at the beginning when she starts to sit, not close to hatch time.
