Aloha @DebbieDee ,AlohaI moved to Kona 3 years ago. Just now back into byc. I’m a bit rusty. I have 5 hens.They are about 2 months old. I have awhile to wait. Question! Will they eat lizards and geckos? I ve seen chickens eat mice. Just wondering.
Chickens don't seem to be able to see the Day Gecko's but love the Morning Gecko's that are quickly dropping in numbers and that are the most native to our islands. I always try to find and feed my gals the super speedy dinosaur ones. I've gotten pretty good at catching them
It is a great source of entertainment... ah er for them. I'd blame it on the "shelter in place" but not so much. Never had any bad reactions from them eating gecko's but I know cats can get sick with too steady of a diet per the vet. Never asked about chickens... 
Nice job! Check out the coop builds on BYC just to see what others have done and maybe see somethings that you can incorporate since you are so handy.
love Orps. The Scarlett Johansson of chickens. I had a few but gave them up, it is just too hot in my area and I did not want them to suffer. Also, mine were SUPER vocal, I knew when they wanted feed or water or a cat was spotted or they needed snacks.. and ESPECIALLY when someone was in THEIR nest box.
One even crowed... I miss them and their beautiful and friendly faces.
