Our girls are 7 - 10 months old. We would like to start free ranging them for a couple of hours on the weekend when we are home to monitor them. My question is - - - - - How do I get the birds to return to the coop after a couple of hours ? ? ? Is it like my cat or dog or pot belly pigs and I just call their names and they will come or do I have to go and collect them one at a time or is there some trick to getting them back in the coop?
