They need some a bit wider for their feet...they like to rest/sleep with feet flat rather than curled around a 'perch'.
Try turning those roosts so the wider side is 'up', make sure they are well attached and stable.
It may take a week of putting them up there before they 'get it'.
That...
Lots of light!
Lots of room to fly down.
Roosts are kind of small, might be 'uncomfortable'...or they might just need 'training' by putting them up there after dark.
Pics of your coop and roosts might help us spot a problem.
Another thing to think about is that if your coop doesn't have lots of windows for light, especially to the west, it can be hard for them to see at roost time this time of year.
