I just ordered 6 chicks. They'll be here in about 8-9 days. I told my hubby I'd take care of the brooder if he'd do most of the work on the chicken tractor. The poor guy has so many projects to get done and I keep adding more to his honey-do-list. So, I'm looking for the quickest, easiest way to put together the appropriate size chicken tractor. The more economical the better. One other question on the tractor issue, at what age can the chicks be moved into the tractor in October/November Michigan weather? Granted it could be 60 degrees and sunnny, 40 and rainy, or it could be cold and snowy.
