Why the pipes? Were those intended to be the roosts when you built it? I'm assuming the chickens like the wood part better since it's wider. Chickens like it wide not skinny and round like other birds.
I have the same feeder! I have found that I need to put an upside down funnel in mine to keep the food moving better and not piling up and getting old in the middle.
I have also made a fermenter for my food.

I need to figure out something to keep the goats out of the chicken run but allow the chickens to come and go when I want to let them free range. Love your idea for keeping them out of the coop. Unfortunately I feed in the run so that's where I need to keep them out of. Maybe I'll build something similar to your idea and attach it to the fence and add a predator proof door I can remove when I want to let them out.
