Thanks so much for the reply. 
They have had very red faces, combs, and wattles for about four weeks now. One is squatting, and I have seen our roo mount one of the hens (not sure which, as they all look alike! Ha!). She seemed pretty willing.
They do free-range all day. They have a well established routine in terms of where they go during the day, and I have checked all of their spots for possible hidden nests. So far, I've found nothing! They range with one other hen and two roos. The other hen is a different breed, and she has been laying for about five weeks now. She goes into the coop and lays right on the nest like a good girl. I am hoping that her knowledge rubs off on the others!
this is the same arrangement that I have and do. My BA's starting laying at 27 and 28 weeks old. Hang in there, they'll come. I live in the same region as far as weather (suburb of Chicago)
