Hey, dont get discouraged.
i can see that a lot of work and thought went into the construction of that.
i also wonder what Netting is on it tho.
i can see it working for fewer chickens like 3 or 4, with a water container.
is it sturdy enough to deter a dog? would you be watching them the entire time?
you may want to think about just enlarging a run to your coop in case someone needs to lay an egg. that way they can get back to the nest boxes to do so.
its nice and lightweight for moving, i do like that feature, but you must think like a hungry determined predator. do you think it will hold up?
