I bought the Windsor xxl 8ft mobile chicken coop and run. It arrived quickly, but I must say that we never received email notification of delivery (so we might have been out!) All was ok and hubby erected the coop and run relatively easily within about 2-3 hours. Liked the spare screws! The instructions were ok but not brilliant. He decided to treat all the wood surfaces before putting it into use...fiddly but we thought wise. The problems started when we first tried to wheel it on a grass surface. It became clear that the coop and run would only move easily on dead flat ground with very short grass...like a bowling green...but who keeps chickens on a bowling green! Once in situ it looked good and were were initially quite happy. Our site is flat with short grass but it's not a bowling green and a few days later when we wanted to move the coop, it again proved to be difficult. My hubby made some wooden rails on which to run the coop wheels without dragging. Despite being relatively well connected, the coop and run sections flex when moved to a new position. This has caused problems with the closing of the run gate. Hubby has therefore braced the whole structure around its base to ensure rigidity and more bracing is planned. We suspect that without all this extra bracing the run and coop would not last for long. We have had a mobile coop on a rough field for many years and it has lasted well. We did not expect this coop to be as robust but we did expect it to be fit for purpose (mobile) on flat ground and in our opinion it isn't.
