I am taking the plunge and switching from Sulcata to Aldabra. I live on a cattle ranch in SE TX and want to build an appropriate tort fence on 4 acres behind our home. From scratch, incorporating multiple “pastures” for rotated grazing within those 4 acres, what fence should I build? Does outer fencing need to be coyote proof? Less inner fencing? Solid bottom portion with what materials since it is such a large area? I want to do it right the first time but without breaking the bank.
