Can anyone give me the basic how to to get set up for electric fencing? We have an 8x8 coop/run under construction with a metal roof. What suppplies do we need to set up an electric fence? Can you buy an all inclusive kit? Also, where would you wire the coop. Around the top perimeter and bottom? Also, we don't want to spend much $, is it expensive? Can you use the same power source that you use to light the coop? Like plugging it into the same outlet? Thanks!
