well he does a lot of online research, Pinterest and Youtube videos give him all the ideas! Since we added a larger run, we had to add another door for them to go in and out from the coop to the run. It's a temporary slider right now but I noticed all sorts of timers and mechanisms saved in the Amazon wish list so he has something more elaborate in mind!
The gazebo was from photos I took from another gardener's yard. He is a handy dandy guy though, totally remodeled everything, except the granite counters, in our last house, built a large shed, arbors and coop here. Getting older and slower though but I have too many projects still so he can't stop yet!
