My chicks are getting really big. They are fully feathered except a few patches on their heads. I have 6 bo, 4 rr and 4bs. They all turned a month old today. They are getting too big for my indoor area and their coop with be finished this weekend minus the run. They haven't been under the heat lamp for nearly a week. I am in South Ga. Would it be safe to put them in the coop this weekend without a heat lamp? I have the heat lamp on my ducklings now and I'd rather not have two running at once. Also, at what age would it be safe for my ducklings to go outside? They are a week old and growing way faster than I thought they would.
