It is possible that the stress from the move and change of environment has messed with their laying cycle, but you mentioned you are keeping them up, do they have plenty of room and are they getting enough sunlight where you have them? Enough fresh air? If your coop is extra hot, then heat stress could cause them to slack off as well so you might want to make sure you have plenty of ventilation for them. Were all 3 Hens laying daily before you bought them? If you don't know then it's possible they are just now getting started on their laying season. Also, if you have deep bedding in the coop, you may want to look around/dig thru the bedding, some eggs may have gotten buried... my Guineas tend to kick and scratch their bedding all over the place when locked up, and often their eggs get buried.
Make sure they are on a layer feed, have access to oyster shell... and if you can, give them greens every day. Sometimes their diet can mess with their laying cycle as well.
Good luck, hope they get back into their laying groove soon.
