I'm a new chicken owner also and I bought the exact same coop! We just got them less than a month a go and they just started laying. I'd say they are getting about 12 hours daylight. They were freaked out at first but now are settling in nicely. We let them out for supervised free ranging in the yard 2-3 hours a day and for pretty cheap (under 50 bucks) I got them chicken wire, posts, and 50 ft bird netting to make a portable pen so they can more safely free range in the yard in the daylight while we're inside the house. Mostly worried about hawks in the daytime.
That's cool you're getting a run for them, that should be plenty of room. I, too, felt bad for keeping them in a pretty small coop so I found a 10X6 dog kennel on Craigslist for 50.00 and a 50 ft roll of hardware cloth at Coastal for 80.00 and some 2X4's and made them a secure run last weekend. I am NOT handy at all, and am pretty bruised, scraped and splintered lol.
