My daughter and I recently finished building this coop, 3x7. We used pallet boards on the outside to give it a barn wood look. We like the way it came out... I have a couple pallet boards as roosts on the left side of the coop but I haven't seen the hens use them. Do I need to build a ladder or ramp so the can get up there to perch? They've looked at them like they want to get up there, but haven't done it to my knowledge. We have 5 hens andI have 3 nesting boxes built in. I didn't think we'd need one box per chicken, but when they go in at night a couple try to double up in the boxes. Should I add 2 more? Also, I have straw down on the floor of the coop. Looks like it's gonna be a pain to clean up. I've seen the posts saying to stay away from kitty litter in a brooder, but would it be ok in a coop with adult birds? I've already modified the ladder with a plywood bottom and more rungs. Newb.
