Someone is in the process of building a peafowl pen for me. I will be getting (2) 2 month old peafowl this weekend. Some of the materials will be from disassembled new pallets that are in excellent shape. My question is.......is there any type of (lead free/non-toxic) coating/sealer/finisher/etc. that can be used on the wood pallets to make it last longer and so that the weather does not damage it from being exposed to the elements? If so, please let me know. I am building a VERY large exotic/safari/jungle/tropical type of pen for my newbies that will have tropical plants, etc. Thank you for any suggestions.
