First of all yes you can make a nice coop out of pallet as you have seen in pics I used pallet as the frame of my coop worked great saved time and money..... Bu to make it easy on you make sure they are in good to great condition if they are broke up their good for fire wood and not much else. and they can be hard to take apart and it helps if alot if not all are the same size. I would say do it if they are in good shape good luck
