No, wear a long sleeve sweat shirt, and pull the eggs out from under her. And keep doing that until you have enough on your counter to set. Then mark those eggs with marker - just an X and set all of them at once.
Every two or three days, using a towel, carefully remove her, and let her go terrorize the flock. Check to make sure that she has not added eggs to the bunch, or other hens have not added. Too many eggs - and the outer ring dies cause too cool, and then she moves them all around, and the 'new' outer ring dies... and get a very poor hatch rate.
If you want to set some of your own, and buy some chicks, you can do that if you match the hatch date with the arrival of day old chicks. Then if you want, you can get some new breeds, or if none or only one or two of your eggs hatch, you still have chicks.
Averages are funny - cause they measure overall, generally speaking, kind of, sort of there is a 50% hatch rate...some are better, some are worse. This summer, three times I set, with a pretty poor hatch rate. I think it was too hot. I have since read that if it is too hot, to use a wedge of grass and roots upside down, and dampened as bedding.
But my point is, if you really want chicks, then you might want to have a plan to get chicks if nothing hatches. (honestly, I am as excited for you as can be, good luck).
