I plan on building a coupe for my chicks but need to know what are some important features to have in them so far I figure they need nesting boxes, a perch, and their food and water should be in cover too right?! I keep reading about poop boards do these go under their perches?! Do I need to make something under the nesting boxes to clean them out or just change the bedding out?! What is the best type of wood to use to construct the coupe and boxes pressure treated, ply wood?! Any suggestions and opinions welcome! We just got two chicks from our local farm supply store I have never raised them before I've been doing a lot of reading an teaching and sharing with my 4 yr old who is in love with his chicks! Thanks!
