I'm presuming your gonna raise them indoors due to the cold weather, this time of year, cause I wouldn't raise chickens indoors, due to the reason most folks have already mentioned. I built a small above ground pen, almost like a rabbit pen, 4'long x 2'9" wide. I put a small cardboard box in it with shavings and a heat lamp. Once they put some feathers on, they were on theyre own and grew up to be my best egg layers. Of course, theyre were only 6 of them and I kept them in the pen for about 8 weeks or so, while I was building coop and run. I raised my next 6 in the same pen, the same way.
