I have had these 6 chicks since they were about 2 weeks old (brought them home 10-28) inside the house. I had to separate them about a month ago, due to to size differences, and cage space. Two are ee's, one RIR, 2 chochins and one Houdan. I really need to get all 6 out of the house as I have 6 more ee's, and a Silkie and two bantam I don't know whats, that are going to need the cages the first 6 are in. So I think the first 6 are now close to 2.5 months old now. The weather up here in the north Georgia mountains hasbeen brutal this winter. I had older chickens(5 months and older) that I moved outside before the bad weather set in, and they did fine outside. I did cheat and hook up a lamp to the cage for a few nights, however. Can I move the chicks out the same way, or is there more precautions I should take since these are younger? Temps have been in the high 30's (if we are lucky) and single digits at night the past 2 weeks (along with the 10 inches of snow that fell Christmas) The weather is suppose to "warm" up the next few days: 47° F | 31° F, 52° F | 32° F, 58° F | 43° F, 58° F | 38° F, 49° F | 27° F. These guys just really need to move outside.
