That sounds smart. I agree about chicken wire and hardware cloth. My least favorite forsure.In the chicken Palace I have a mixed approach. It is mainly lumber (although in construction it felt like it was mainly harware cloth that stuff is such a pain to work with!) but we used plastic lumber (made from recycled milk bottles) instead of treated lumber in areas most likely to be in direct contact with grade.
I really hate treated lumber and would have used more plastic lumber but it is quite expensive particularly for structural framing lumber.
