Unlike most coop plans out there, our coop only cost around $300 to build. We didn't want to spend a grand on something that would literally just get crapped on. We used a few tricks to save money like buying stucco netting instead of chicken wire. They are the exact same product but stucco wire is about half the price. We also used particle board instead of MDF, cutting down another $200 dollars or so.
Like I said, it still needs quite a bit of work. But it's functional and my chicks are happy with it so the rest will have to wait for a day I'm bored this summer. Also, if you live in the area and need fresh eggs, I'll have them coming out my ears around Christmas.
