Yes, move her if possible to a setup where she is the only hen with access to that nest.
Wait 1-2 days after moving to give eggs, if she has been sticking to the nest day and night. If she gets up often, paces around letting the eggs get cold. wait. She may eventually settle down and sit tight.. that is when you give eggs. Some hens sit tight the whole time or some take a while after a move.
With isolated broody hens there is no need to check on her. Being gone for a few days or even a week is no problem.
With the set up she originally started on, that is a problem even with daily checking. The other hens are bothering her and will have a fair to good chance of getting the eggs broken when they try to lay their eggs in that nest. Being gone for 2 days could be a problem if the hens add so many eggs she cannot cover all of the eggs, possibly getting the intended eggs killed by cooling down.
If the rooster is breeding the hens normally- not struggling due to size difference or something like that, it is safe to assume the eggs are generally fertile.
It is a good idea to candle the eggs at a week to check for fertility. If they all or mostly fertile, you can leave and remove the infertiles. If the eggs are not fertile or too few are(just one or two), remove ALL eggs and do a total replacement with fresh eggs. Do not be tempted to leave the one fertile egg and add new eggs.. the hen will not stay on after the one chick hatches.
