Thank you!
Currently, there are 3 that sleep there - I have 1 Australorp, 1 red sex-linked, and 1 Wyandotte, all just over a year old. Next month, I will be adding 2 "Alchemist Blues" from Alchemist Farm (as far as I can tell, they're mostly Isbar/Silverrudd Blue), and I'm thinking of including 1 more chick - standard to large breed to that group, (right now leaning towards a Marans, or possibly a Bielfelder, since I'm really tired of dealing with accidental cockerels that I can't keep). I know I need to add more roost space before they're added to the roost situation.
I had heard that height, though I've definitely seen pictures with minimal distance between roost and drop board from people on here who seem to know what they're doing, as long as they're above the nest boxes. Part of my thought was ease of cleaning - both in terms of the lack of splatter and my ability to reach it (the coop is elevated already), so that's what I started with. I can definitely play with the height to see what happens - the easiest being just getting rid of the drop board and leaving the roost bar at its current height before I try anything else.
It seems like the easiest would be to set a second bar just above the top of the nest boxes parallel to the current one Do you see any other options? Diagonal would be difficult and not allow as much distance between birds on one end.
If I do the parallel one above the nests, is there an easy way to protect the space below the nests so all that poop doesn't get tracked into the nests and make the eggs a mess? Would you just make a roost frame like you show that doesn't go all the way to the nest box, instead of attaching the roost to the wall? Or adding some kind of roof material under the 1' in front of the nests? Or both?
