A change in environment can cause them stress and to stop laying. Moving home can certainly knock their laying. They likely laid the day you got them because the egg was already made and ready to be laid. It takes the hen 24 hours to produce an egg. This will have started prior to you picking them up.
With time and once they feel at home they should start up laying again.
