I received 4 5-6 week old chicks last Wednesday. Two EEs and two Barred Rocks. The two BRs didn't do well with one dying Thursday and one dying Saturday. The EEs have been full of energy since day one, but I treated with Corid to be on the safe side. I have two more 5-6 week old BRs coming tomorrow. I have the EEs in a temporary run in my garage. I planned on putting them in the permanent coop tomorrow, and let the BRs spend a few days in the garage. Is this the better way to do it, or should I keep them all together in the temp run in the garage and put them all in the permanent coop together in a few days?
