Hi Everyone! Newbie here! My chickens are all about 15 weeks, and they have a big coop/Run but after reading so much on BYC I decided I would let them free range for a few hours each day (I would love to give them more time but my dogs are crated while the girls enjoy the day) Sooooo, I just opened up the coop and let them out! I'm a nervous wreck, will they stay close? How can I get them back in? It's a beautiful day here in southern Ca and we are on 10 fenced in acres. Nervous newbie here! Any advice for me?
