It's easiest to wait until it's dark if you need to catch/move the girls. If you can put them in the coop/on the roost after dark they should stay put until morning. You may have to confine them for a few days or only let them out in a fenced run so you can get tem in at night and then see that they put themselves to bed a dusk. Once they do that, they know where home is and return to roost/sleep and hopefully lay eggs there
