Originally, I was planning on building my coop and then ordering chicks in February. However, I live in an area where the average low temperature in winter is 35 degrees, which is nothing compared to the North East (or Chicago, where I moved from). Do you think that the chickens would be fine if I ordered them soon? They would go outside before the temp even got down that low, then they'd have a couple of months in the 30s-40s before it'd start warming back up. Thanks.
