Yes, as far as the deer go we do understand that they can jump a typical 6 ft. fence. But when using multiple stands of electric wire, using black fencing (black throws off their depth perception we read somewhere) plus possibly tipping the top inward we are hoping to cause them to think twice because of the poor depth perception. I can't find the article we read before but the link below is a good one from your neck of the woods Bruce.

We have a small apple orchard fenced in with 6' black wire and never in over 10 years have the deer jumped in even though they sleep around it dreaming of the apples within.![]()
Bruce, your ground is the opposite of ours. We have sandy loam until you get down a few feet. Then you hit hard clay.
Interesting that you can screw up the deers' depth perception. Useful too since shorter fence is also cheaper .
If they don't go in for the apples, I really doubt they will go in for whatever might be in the yard where the chickens will be. The chickens wouldn't leave anything the deer want

T posts for 6' fence? How do you get enough vertical stability? Might be a question for DH

Sandy loam over clay huh? The difference is we have rocks IN clay
