I currently have 8 Rhode Island Reds that are approximately 8 weeks old that have been moved into my coop. My wife also picked up a mix of 15 Sapphire Gems and Easter Eggers this past weekend at Tractor Supply. The new chicks obviously will not be able to go to the coop for a number of weeks, but I was wondering if, when the time comes, whether they will be close enough in age to just put them into the coop or if there is a specific way I should go about introducing them. Coop/run is probably close to 600 square feet total pretty evenly divided between coop and run as I converted a shed into the coop.
