Ya moving them like that will easily stir them up and cause them to stop laying, it's a form of stress being thrown into an unfamiliar environment, not much different from being scared by a predator attack can shut off their laying for awhile. If they don't start up after getting settled it might not hurt to switch to a no calcium feed as it can cause problems in too high of levels however many people have fed layer to the whole flock regardless of laying, not laying, hen, rooster, chicks, etc and not had a problem. I provide free choice calcium no matter what type feed I use and I'm going to switch to a higher protein feed and quit the layer anyways because I have found the higher protein feed lasts far longer, they self regulate it and eat less. The higher end feed only costs a few bucks more but the volume of consumed feed is going to save me money.
