Information Please

I bought a rooster and a hen at a recent show I visited.They Certainly seem to look like the pictures you guys closely. They are a rooster Grey and a hen which is white with a Grey edge on her tail.They were said to be one year or last year's chicks which I figured was yearlings . The hen has not started to lay however. She has been here about three months and she and her husband seem no more ready to start a family than my little girl who was a gift from a very nice breeder . I am not really interested in breeding but I do like the Lavenders.

1 What is the laying season for these guys. Is something wrong with her that she dose not lay?
Do I need to checked out for problems because she is not laying?

2 They are so cute together . I am afraid watch them by the hour . I have them in my bedroom in a four by four pen and I let them out when I am in there with them.
