I tried to search for an answer but couldnt find what I was looking for. Several days ago I moved my guinea keets from the "brooder" to the coop. Inside the coop, they are in a 2ftx6ft pen. The pen is just a 1"x2" wire fence, so they are able to see the chickens. They have been constantly pacing the wall of the pen. They are still eating and drinking, but very determined to find a hole in the wall to escape. I tried to surround the pen with cardboard to make it appear to be a true barrier. Well it stopped the pacing, but they went NUTS and started "peeping' like crazy! I was impressed with how loud they got!. They were content in the brooder and rarely made a sound. Should I just let them out of the pen to hang out with the chickens? The chickens range between 6-8weeks old. Recently (yesterday) I re-homed several of the 8wk old cockerels. Before, the older chickens wanted NOTHING to do with the younger group and would constantly pick on them. Since the cockerels are gone, all the older pullets have really calmed down around the younger group (which consists of cockerels and pullets). While I dont know the exact age of the guineas, I believe they range from 3-4weeks old (possibly older). As far as the size difference, they are very close to the size of my 3 bantam pullets, but still smaller than the Red/Black Star pullets as well as the younger flock (which consists of 5 polish and 6 turkens). If I let them out, they would have access to the coop (10x10) as well as a fenced in 12'x24' fully covered pen. I do want to eventually free range all the birds with them going into the coop at night to sleep (including the guineas). Would letting them in the coop and run hurt the chances of them imprinting the coop as home? Thanks in advance for all the help! I will be trying to get pictures of them tomorrow (it was already too dark in the coop to get good pictures of them).
