Breeding is still going on, and will be for another few weeks. Can't see the wing coverlets to tell if that is a jenny or an adult hen, but I am certain it is not a female from an early hatch this year. That female is at least 6 months old to have adult plumage, but probably at least 9-12 months old. And hens don't set for males just for fun. They only set when they are ovulating and producing eggs, so I'm sure she is about to lay or has already started laying.
