Would you please post what region you live in so we know what climate you're going to be dealing with?
The easiest thing all around is to brood right in your coop. That way the chicks grow up where they will be living, imprinting on it so it cuts down on the stress of moving them in later.
I advocate training your chicks early on to come to you with verbal and physical cues. I recently trained my two two-week old broody-raised chicks to come to me. It took just a day and a half and they now jump into my hands when I show them the cues. Here's how I did it.
I first got them hooked on meal worms. You may give small, tender meal worms to chicks in the first week after hatch as long as you provide grit. Some chicks are suspicious of these treats at first, but it won't last long.
Sit down on the floor or ground with your baby chicks. It's important to be on their level. Once your chicks know what meal worms are, place the meal worms in your closed hands. When the chicks are paying attention, open your hands to expose the worms inside. Allow the chicks to take them from your hand.
As you repeat this fun activity, speak a verbal cue you've chosen. I just say, "Come here." It doesn't matter what word(s) you use. Very quickly your chicks will associate your closed upturned hands with treats. To get them to come to you, merely stoop down, show them your closed upturned hands and speak the verbal cue. They will immediately assemble in front of you like a platoon of Marines.
