I've read about slanting the top of the nesting boxes to prevent chickens from perching there and pooping on top of the boxes. But I've also read about giving the inside of the coop fun things for the chickens - like extra surfaces, shelves, logs, for them to climb on and entertain themselves if they ever had to spend extended time inside. So these pieces of advice are in conflict with each other... If the sleeping roosts are the tallest structure in the coop, will that encourage the chickens to sleep there and leave all other surfaces for play only? Can I leave the top of the nesting boxes flat just as another surface for them to climb on, just for fun? Is the slanted top advice specifically so they don't sleep there at night, or in general? Do you have any other climbable structures/surfaces inside your coops besides the sleeping roosts (and poop boards)? I'm hoping the chickens will spend most of their time outside, but in case there's a big storm or something, and they have to stay in for a while, I want them to have things to do. The nesting boxes are an easy surface since it's already going to be there, so less for me to add...
