I will have help. I will confer with my boyfriend what he thinks. This is for the chicken run, which will have space under the coop, which is 20'X10', so I will need at least 3' of wire to go around that portion (including burying it), and then the remaining run is also 20"X10", and I wanted at least 7-8' of wire around it, with the rest being covered with plywood (to save money on fencing). There will be a metal roof over the run. I will have a lot of money in fencing materials, but predators, especially bears, and coyotes are an enormous problem. There are plenty of racoons too, but they have mostly been occupied with my garden and not the chickens.
