I've seen a few "fence height" threads around, but I thought another wouldn't hurt, just in case anyone has additional suggestions 
We'll possibly be moving to a 2 acre horse farm (no horses on it) in a month or two, and all the girls will be getting even more space. They're currently in a 8x8 pasture pen that gets moved daily.
The new house comes with 2 pastures (about 1/2 an acre each) fenced off with 4 board board fencing (it's between 5 and 6 ft high, pretty sure it's 6), and we'll be putting the girls in one (and converting the pasture pen to a coop). We'd like to put up welded wire on the existing fencing to keep dogs out (as the county doesn't have a leash law, and there are plenty of dogs in the area running around) and help keep the girls in. So, questions are:
Is 6ft high enough to keep the girls in? I know it's high enough to keep most dogs out.
Any extra precautions? The farm has a few neighbors, and the entire thing is surrounded by woods, so while I already expect hawks, I wouldn't be surprised if a couple nested nearby.
Thanks for any help
