I'm a first timer and I'm getting ready to start a small (4-6 hens) flock. My landlord doesn't want the chicks inside at all and I just don't have a good place in the garage for them. So is it OK to set up a brooding lamp in the coop and just lock them in the coop with plenty of straw until they get their feathers? Or should I just hunt down some juvenile birds so they can go outside right away? Other than the few rainy nights we've had it hasn't been below 65F at night.
