My broody hen is setting on 7 hopefully fertilized eggs. She is currently in a large pen, inside of a coop with 5 other hens and one rooster. To keep the other hens from bothering her, she is in a large dog cage with food and water. My question is what should I do when the chicks hatch? I don't think I should keep mom and chicks in the cage for a few additional weeks, mom probably needs some excercise after setting so long. How do I feed the chicks the food they need while keeping the adult chickens away from chick feed? Do I isolate mom and chicks from the rest of the flock? This is obviously my first experience in letting a broody hen set on eggs. Any advice will be GREATLY appreciated. Oh, my coop is 8' x 12'
