We followed all the original plans and added a few modifications. Chickens seem happy! We dropped the height of the nesting box down a little and made the roof only cover half of the coop. We live in California on the central coast so it doesn't get too cold. We also only made one side of the nesting box able to be opened. We added a little door on the bottom level with left over t 1-11 for easy access to their food and water and in the hopes that eventually we will let them roam our yard supervised during the day.
All in all the project cost us about $150 and took 4.5 hours to complete! Thanks for the great plans!
