Bird scare tape

[o2bgreenntx]

Have just witnessed my EE (almost 9 wks old) fly to top of garden fence (4 ft).
We let them free range in fully chain link fenced garden/orchard area approx 1/10 acre, it is heavily treed on 2 sides, human abode and quiet street on the other sides. Don't want to clip wings, wouldn't do much good anyway as I have read. We have witnessed several hawks in the 6 months we've been here.
Question is would the vinyl reflective "scare tape" tied to top of fencing be effective to keep my girls off the fence? I have it in my fruit trees and vines with good success against wild birds...so far.

The birds are penned so they are not free ranging. You are trying to prevent free ranging.

Clipping wings absolutely does help. I had to do that to my original flock when they were first confined to their pen as they were flying up to the gate tops and jumping over. I did a bi-lateral clip into the secondaries on most birds to keep them in. Once they acclimated to the pen, they stopped trying to escape.
When their wing feathers molted back in, I didn't have to clip again.
All subsequent chicks growing up in the flock have never even thought about escape. They stay in there with the others.
I even came home one day to one of the gates blown open because it didn't latch correctly when I fed the birds in the morning. Not one single bird walked out that gate and they had hours to do so.
