Yes, if they have some distance to flap their wings on the way down, I think it would be fine. my poo tray is 20" wide I have the roost approx. 3" from the front. most gets in the tray, a couple like to face the wall so I end up just picking a little off the floor every day when I clean the tray. they spend all day out in the run except for when they are in the nesting boxes so I don't get anymore poo in their during the day. If you have a ramp, I would stick it up and give them a choice. I have a gold comet, buff orpington, 2 SLW, and 2 EE. the SLW's, one EE and the Buff orp are big. I don't ever see them fly. I have a roost branch outside and they always walk down to the lowest part to jump off. Now this is just my experience, with my big girls. if others are fine jumping from a higher height, fantastic!
winter set up, upper tray taken out to get them out of the draft of the vents. Don't mind the mess, as i'm in minnesota, and it was my first year with chickens, I did alot of experiments. here they were putting themselves to bed, as you can see, no poo on the floor as they never spend time in the hen house. 2 are facing the wall. This roost is 4 feet long, the six of them just fit (big girls). I mix sweet PDZ into the shavings on the floor as well. I poured a whole bag on the floor, then mix it around with the shavings. helped to keep the humidity down in there as well.
Summer set up, I remove the lower roost, keep the tray in there so they can jump down to that, then the floor, I don't have much area for them to fly down. they always jump to the lower tray, then off. they will jump up to the upper tray with no issue though.
here is when they were little, more than enough room, right? lol
Their branch in the run, they usually walk to the lowest side to jump off.
