If your rooster keeps sleeping in the nest box, I'd try to assess why they're not going up to the roosts - it could be an issue with the pathway up/down from them, it could even be an aggressive hen who's more dominant.
I currently have a bantam buff silkie rooster, for a while he got picked on by the older hens, but he definitely sleeps with all the other hens 6ft up in the air on the roost bars in the run. Have had other silkies in the past and they got up/down from those roosts without issue either. I do have a ladder system for them to use, but he can definitely jump/fly up like 3ft
IMO an auto door is semi-pointless if your coop is setup inside a secured run that they're penned in daily.
