Thank you everyone for your replies. They will come in handy for the upcoming transition. I feel much better knowing that moving outside is doable at this time of year. They will move out of the basement (that will make MY life much better, the dust is killing my lungs) into the unheated garage...
I was given some chicks back in mid December (long story). I was wondering since they are feathered out if it possible to start getting them transitioned out with the big girls....
