Moving her will break broody cycle. A broody will stay in clutch at night. A day or two before broodiness truly sets in she will stay on nest for extended periods about time she deposits an egg.
That's not entirely true.. if your hens are used to being touched and handled (like mine are) they won't be especially bothered by being moved. Heck, I once carried one around in her nestbox while I was prepping a dog crate to put her in. Plus.. if a hen is determined to be broody.. a little thing like a human messing with them isn't going to deter them. In fact.. that's one of the tests I use to make sure a hen is actually serious about being broody. I lift them up, carry them around, tickle them, muss their feathers, toss them (gently!) from the nest boxes. If after a week or two of that, they're still broody, then I decide that they're serious. I then either wait it out, or buy eggs for them to hatch and sell the chicks.
