Hi! I designed my coop and had someone local build it. I didn't give a ton of info/direction on the roosts, other than I wanted to be able to remove them if needed. I've known all summer that my roosts weren't exactly "right." But haven't really figured out what I want to do to fix them. Realized I should just post on here and see if anyone has a great suggestion, as so many of you have been crazy helpful to me in the past! 
Hopefully my nerdy sketch of the layout is helpful. It's a 4x6 coop and currently, I have two roosts that run along the opposite side of the nesting boxes. Originally, there were two long/narrow roosts, one upper and one lower (you can kinda see in the photo on the lower right). I realized they weren't as wide as I wanted as my chickens got older/larger. So as a temporary fix, I removed one of the triangular shaped pieces from each roost bracket (the braces holding the roosts in place) so I could lay a wider, rope wrapped roost across the top (as seen in the bottom, middle photo). Obviously that's where my girls want to sleep -- it's wider, it's comfier, and it's higher. The lower roost is a pain every morning because it's too close to the higher roost and gets pooped on all night. I am hesitant to remove it though, as my RIR is the least coordinated thing I've ever seen (haha) and often relies on the lower roost to help her get up to the higher roost.
I keep thinking about running my roosts across the coop going the other way, going 4' across - attaching the ends right below the windows. I can't run a lower roost across that direction, as my nesting boxes are on one side (no wall to mount it on). So I think I would need to build a mini ramp up to the roost? Or at least partway up, so my RIR has a little help each evening. I don't really want to take up a ton of floor space, or make things harder to clean/inaccessible to clean. Any advice on how to go about this? Or do you have a completely different solve? I may be overthinking/overcomplicating this (my specialty)! Thanks in advance!
*Also considered adding a roost even higher, along the top sides of the windows going across 4' -- but the metal roof takes up a lot of room at that point, so not sure if that would be a waste.
