Purchased this coop a little over one year ago for 6 medium sized hens. The plastic is still quite sturdy and was never brittle in the cold (we're zone 6 and at elevation), and the latches are all still in great shape. It's exceedingly easy to clean; I blast it off with a high pressure hose roughly 2 or 3 times a year. You could even break it all down and scrub it back to brand new if you wanted to. Ventilation is acceptable, though I often keep the door open at night (in a secure run) to help with airflow in the summer. When building a frame to get it off the ground, I strongly recommend a central 2x4 run perpendicular to the floor seam. I'm adding that support to mine this summer as it's begun to sag and I don't want anyone falling through!

Overall it's pricey, but it's well worth the extra cost. This thing will last longer than my chickens.
