Silly question...what's a daytime roost? Is that a lower one?
It's just a roost out in the chicken yard. I just have a 2x2 that I slide through the fencing holes in the chicken run (the covered part of the chicken yard). The chickens like to sit on it in the mornings first thing when they come out of the coop. Mine is only about 3 foot off of the ground, but it's adjustable since I just slide it through the fence.
At the moment I'm using it to support the light in the shed for my newest babies and broody.
