I believe it was Bettacreek that said she holds them and lets them 'run' until they wear themselves down, then lets go and they stay there. She must hold them for a while, cause mine never seem to wear down! Good luck!
I had a similar problem trying to photograph my bobwhites right out of the incubator--once I put the chick back in with them that they thought was "mom" I got them to hold still for a second
