I bought my baby chicks at the beginning of September, they are now about 4 weeks old. From what I've read, they would be moved to outside housing around 6 weeks or when their heat lamp is at 70 degrees. This assumes that it is 70 degrees outside, which is probably the case when you have chicks born in the spring. Any suggestions on how to go about this now that it's fall? Average temperature right now hi 68, low 40, here in Oregon, but I'd say it's around 50 most of the day. I do take them outside for an hour or so each day, and they are quickly out-growing their enclosure in the house. We do have a simple greenhouse we built, but I'm not sure if it gets warm enough in there either, especially when it's cloudy and rainy like it's been, but I can run power out to it to maybe set up their heat lamp in there? We also have a garage but it's not heated. either way they definitely need more space soon!
