We are contemplating the idea of going with a cold frame structure for our chicken run (obviously w/o the polycarbonate panels/). What we're thinking at this point: Run welded wire mesh 5' up the sides (all sides), and cover the rest (up & over the top) with heavy-duty aviary netting. We'd also electrify the wire mesh to keep anything from climbing up it to get through the aviary netting. Would I need to run an interior perimeter of chicken wire (or similar) to keep the chickens from touching the electric fence/mesh? I'm worried about them getting zapped & wasn't sure if they could withstand something like that (and hopefully learn not to do it again), or if it's best not to give them the opportunity to come into contact with electrified fence. Please feel free to pick this apart, offer any advice, etc. We'd like to give our birds quite a bit of space in the run & want to make sure all of our bases are covered before we finalize the plans (and the ground thaws). Thanks in advance!!!
