No, I wouldn't jump to that conclusion just yet. Mind you, chickens who are stressed from a new move and new home won't lay for a while. Also if you buy new chickens and bring them home they may lay for a while and then stop. My blue hens did that. I have 1 of 3 who is still laying. The other two did for the first two days and then stopped. I'm waiting on them to pick it back up.
My Ameraucanas were tailless when I brought them home and now that I've taken out the mean dark hen and left the much more docile hens with one roo and put the mean hen with another roo, they've started laying. I've had them for several weeks though and only this week have I gotten eggs from them.
