They do free range. I can never tell with red combs; to me all my hens' combs don't look overly red, including the ones that are laying. My BR hens have tiny combs.
I have several breeds that started laying at 4 1/2 months to 6 months but my barred rocks haven't laid yet and my New Hampshires laid a few pullet eggs a month ago but haven't laid since. I don't know why they didn't continue laying; they're 6 months old.
