The ABC's of baby chicks please!

[dudebro911]

We have 6 teenage chicks now which we think are possibly all roo's, but one. They had all begun feathering when we got them and we had them living outside almost immediately.
Planning on adding to our flock with babies that have yet to feather out. Our coop is sheltered outside here in South Carolina where it has been ranging temp wise in the high 80's-90's in the day and 70's at night.
With that being said...wondering what all we need as far as a brooder box? Should we start them out inside, and if so...at what point can they be moved outside to a box within our coop? Can they start out there? If they stay inside what all do we need?
Just need some general direction.. as this is all new!

Whether they're inside or outside is your choice, but they are going to need a heat source at first, especially at night. General rule is to start out with them at 95 degrees and decrease by 5 degrees per week for the first 4-5 weeks (until fully feathered). You'll need to keep them separated from your older chicks until they're of similar size, and then get some advice on how to integrate the two small flocks. I suggest using Sav-a-chic or some vitamin/electrolyte mix when you first get them, especially if they're shipped. Dip the tip of their beaks in it as soon as you get them to encourage them to drink as they may be dehydrated from shipping.
