Do you know of anyone who got a prefab from My Pet Chicken?Ask around at your local feed stores for some one that builds coops. Also, in my area at least, there are a number of folks on craigslist that build and sell coops. They are pricey, but figure your cost for materials and hours of labor if you did it yourself, and the cost seems pretty fair. Sometimes you can find used coops for sale also.Prefabs depend on the manufacturer, some are pretty good, though small. Depends on your desired number of chickens, and your weather. I like my prefab, but it was too small, so I built a new coop. Now I use my prefab for quarantine/intros.
I would put the build quality of my OverEZ coop against any custom made coop. Sure, there is room for improvements (like ventilation) but it is SOLID and made of real, quality lumber. My first coop was a typical prefab made out of miniature planks of very light “fir” and while it made an OK grow out coop, I could tell right away it wouldn’t last more than a year. And, it needed a good bit of work just to not flood when it rained! The OverEZ is weather proof from the start and fully painted with Sherwin Williams exterior latex. The interior wood is sealed from the factory as well. As far a predators, should be 100% safe from anything except bears. The window screen does need hardware cloth but that’s it.
