We have lots of predators ; bobcats, opossums, raccoons, coyotes, etc. So before we built our coop, to protect our little ones, we designed and built this chicken tractor on wheels for the baby chicks to roll around the yard in until they were large enough to fend for themselves. the roof is off of it to show you the angle and the interior heat lamp. It has served us well over the years to protect the little ones from harm. Once we found the wire pulled heavily on the end but not broken by a creature. so the metal may look awful and not so aesthetically pleasing.. but it functions well.
