No, but I added an egg box to an existing one, and built several runs.
Chickens really don't care about the amenities, they just want a bar to roost on, and need something secure that racoons can't get into.
Either a solid wood box, or a wood frame covered in chicken wire, with a bar suspended a few feet off the ground, and a latchable door, and you got a chicken coop.
The fancy designs are meant to appeal to humans, not chickens. Ours have slept in a 5ft tall, 3ft wide, 1 ft deep wood and chicken wire box for about 3 years. In the day time they run around in the run.
We put a little solar powered motor on a timer that opens the door at sun up, and closes it an sun down, so all we have to do is keep feeder and water topped off every few days and collect the eggs.
How many do you have that you need a bigger coop? Do you make them stay in it all day? Most predators only come out at night, and the day area only needs to be secure enough to keep them from running amok.
When we had 6, all 6 would croud together on the top bar, even though there were 3 perfectly good roosts (and all 6 only used one of the two egg boxes).
Now that there are only 3 left, they still all crowd together, crunched up into a corner on the same roost.
Unless they are all packed wing-to-wing, don't assume they will even use more space if you gave it to them, chickens are not like people in that way
