I have moved my 3 young ones outside. They're almost 6 weeks old and they've been outside for nearly a week. It's my small coop/run, the type that goes under the stairs (coop) and a run that extends out about 10 feet, that I have set aside for young ones before integration. My idea was to turn off the heat lamp in the coop during the day, but back on at night because our nights are consistently in the 30's now, with a few nights in the 20's and some in the 40's. Two of them seem to have completely feathered out, and the 3rd is nearly there. I'm now ready to try and wean them off the heat lamp at night. I'm thinking about turning the light on about an hour later every night until they are going through the night without it. While it's cold out, there is very little room for draft, and there is a good 6 or 7 inches of already composting pine shavings in there. The two that have feathered out are being given as a birthday present, probably in a week. The other, right around that time, will be integrated into the existing flock of adults. Any thoughts?
