Oh, yeah, that's probably it then. Introducing more chickens always stresses them out more than they let on, enough to stop laying for a day or two at least.....Well my 3 pullets just started sleeping in the hens coop the night before they boycotted laying. They had two separate coops for a month but had access to the hens coop. I guess they finally felt like they merged as one flock. That could be it. I was just so excited that the pullets finally moved I didn't even think that it would effect the hens laying. Thanks for pointing that out ibarbidahl
