Go larger on the pulse charger (higher the juole the better or a minimum 10 mile+ system) maybe even a solar charger system but try to go with a system that they touch one wire and they get zapped
(the two wire system requires double contact and is more suseptible to shorting out).
To set it up clear / mow the perimeter where you're running the fence, be sure there is no way to climb around it (trees with low overhanging branches, climbable buildings etc) look into using step-in pre-insulated posts, set the bottom strand about 4' off the ground(not the grass), set the second strand about 4" above the first, then run 2 more strands evenly spread with the top wire as high as the posts will allow. Read the section about the ground rod and keep the ground rod area damp for the best results. The yellow polystrand fence wire is really user friendly.
Don't worry about the birds getting shocked. I had a fence last year that was so hot it almost rolled my 500 pound hogs
and caused a goat to do a back flip
but the chickens walked right thru it to steal out of their trough, a few got shocked but all they did was squacked and walked right back thru. If you need to contain the birds inside a hot wire, for their safety, throw some deer netting on the EF to keep them from walking thru. (goats and sheep will probably touch it occationally but they learn fast and it does not injure them)
Done right, don't worry about hot wire on the top of the run. But if you insist, run a insulated wire to the run top and hook it into the same charger.
Make sure you walk your fence about once a week and after storms to insure it's not grounding out on a branch or trash.
