I have two barred rock girls that are about 12 weeks old now. I have had them since the were one week old. They have always been together. I would have to pick them both up together as chicks because they always liked to be able to see each other (or they would freak out). For the last 4 weeks, they have been outside. I have a coop inside of an enclosure, and they are in a covered puppy pen also inside the enclosure. The coop is home to 3 buff orpingtons and 3 ameraucana that are a little over a year old now. They have not acted aggressive toward the barred rock. They have gathered around to watch them eat sometimes. I want to let the barred rocks free range with my other girls, but I was concerned that instead of staying with the older girls and learning from them, they would want to keep to themselves. Should I try keeping them in the enclosure together before letting them free range. I have 5 acres and am worried that they will go off on their own and get eaten by something or lost in a cornfield.
