I just took a look at your last pics to check the comb color....the one hen looks like her comb is fairly red, but maybe not red enough. Also, newly moved hens can hold off on the laying for a couple weeks til they get used to their new digs. So give them some extra time for adjustment. Put some fake eggs in the nest boxes too so they get the hint and when the time comes, they will know where to lay their eggs.
