Anyone successfully use metal shelving as roosts? We temporarily added one 5ft metal shelf along the back wall with a ramp leading up. I have a frizzle that can not fly. The shelves are currently 14 inches thick and have nice sized slots for the poop to fall through. The chicks loved it, so I'm thinking this may be their permanent roost. We are going to switch out the 14in width and install 20in width near the bottom and place the 14in width to the adjacent wall higher up. The only problem is I don't want the chicks to leave the frizzle stranded at the bottom. I could add another ramp leading to the top I guess. We will hang a nice heat lamp during the winter, so it won't be too cold. I have a d'uccle that is not winter hardy. Here's a picture of what we did. Our coop is not fully finished, we are finishing in the fall when we have time. I do not have poop boards, so I threw DE on the floor.
