My chicks are between 2.5- 3 weeks old, but two seem to be much younger. We bought two groups of six a week apart, and two of them look as old as the original six, two are almost as feathered and two only have feathers on the outer half of their wings. They are currently in a metal stock tank with a heat lamp on one end and about one foot above it I'd like to move them to a much bigger enclosure in my garage. There's no heat out there, so I'd still use the light. I'd build the enclosure in a corner so I'd only need to make one side and an end. The floor is concrete, so I'd put cardboard down and then use Klean Koop and shavings as bedding. The issue I have with doing this is our night time temps are still pretty cold, and will be going down to 16F this week. Daytimes are low 40's up to mid-50's. There's not likely to be much change in that over the next month. So, should I do it? I need them to have more space and the chicken dust is going to be a bigger issue over the next few weeks because they do a lot more wing flapping now.
