Do you know how old they are? Are they molting? If you move hens (or they get upset for some other reason), they will often stop laying for quite a while, so them not laying right now is really not that unusual, if they doesn't go into a molt because of the time of the year, they should start up again probably within a couple of weeks. It does take chickens a little while to get used to their new homes, do you know if they were allowed to free range where they came from? If they have ever really seen the outdoors? They should gradually get braver, you might try feeding them some scratch/treats near the door and then throwing some outside to give them some incentive to go through the door. Chickens do have a pecking order and there is usually one chicken who is in charge, and often can act as something of a bully, as long as she is not drawing blood or really hurting the others I would let them work it out... they have to sort them selves into some sort of order since they are in a different group at your house than where they came from. You are sure they are all hens, they didn't give you a roo?
