A broody hen will let the egg gathers know that she is not happy about them trying to take her eggs. She should kind of look like a mad hen and peck them. So they should pass Miss Broody by. A chick hatches in 21 days, so things start happening soon if the hen is setting one the eggs. You might find it interesting to candle the eggs.
But, I don't think you will have a problem....as said, people don't want to find that surprise, so she must not have any problems.
