That looks pretty nice. I think it will work fine for six hens since they will have access outside.
I'm not sure where you are located. My main concern would be in the summer if you are in a hot climate, but more ventilation above the chickens in the winter does not hurt. Chickens can handle cold much better than heat as long as they have adequate ventilation and are not in a direct draft. That means in the winter, the ventilation needs to all be above their heads when they are sleeping.
In the summer, you can provide more ventilation above, at the same level, or below the chickens when they are sleeping so they can stay cooler. I don't know if you can open your window in the summer, but that would be nice. That poop door will be open during the day too, winter or summer, so that will be a big plus in the summer, but you might want to close it in the winter at night. Open in the winter during the daytime should not be a problem. I like the way it opens up for easier cleaning.
Do you plan on having bedding on the floor? If so, you might want a lip at the openings to keep the bedding from being scratched out. A removeable lip would be real handy for cleaning.
If you will have bedding, you might want to raise your nest boxes some to keep them up out of it. Otherwise, they might scratch a lot of the bedding into the nests. That's probably not a big deal unless the bedding has fairly fresh poop in it. Of course, if you raise your nest boxes, you need to raise your roosts.
Another potential issue with your nest boxes is that the chickens cannot get under there. That could become a great place for Mommy Mouse to raise her family and stay close to the chicken feed. If you don't have bedding it probably won't be an issue, but you might want to consider fixing it to eliminate the possiblity of a mouse. In that coop, I'm not sure you could raise it enough to allow the chickens access. If the chickens can get to them, they'll eat the mouse and her babies, so I try to always provide them access.
It probably sounds like I'm being critical. I don't mean it that way at all. I think you did a great job. You probably have enough ventilation, but I'd suggest if you are where it is really hot in the summer, you pay close attention to that. The mice and the trash in the nest boxes at a low level, well, I've had experiences with those. That does not mean you will. It is just a possiblility you might want to be on the lookout for.
Good luck!!!
