If you are thinking about just building a smaller coop, you might even be able to get away with using recycled timber instead. Asking around for scrap pieces of wood can also be one way to locate some materials to use, but bear in mind if youâre going to go this route there is a higher chance youâll have to pull some nails and may wind up with a chicken coop that isnât exactly matching. If youâre really looking for the absolute most cost effective method though, then itâs likely something that you will want to think about and consider.
