I second the double
fence idea, especially when used as a
chicken run. The pest controll, use of space, and deer protection is outstanding. I live in one of the highest deer populated areas in the nation. If you consider our registered hunters a militia, it would be the 4th largest army in the world. Double fences work. The chicks love cleaning up the hard to clean fence line, and weeds and scraps from the garden are an arms throw away to
feed them. If properly graded, the run can wash their nutrients directly into the garden. Plant sunflowers, amaranth, corn, etc and climbing squashes on the outsides of those runs, and you have a nice little nutrient flow,
chicken feed, chicken poo, cycle that works beautifully. Oddly
enough, Deer don't really like pumpkin like vines and sunflower...near me atleast. They are too jabby-hairy-spiney. And the amaranth, well they just plainly have shown no interest in. I say quinoa and amaranth, because they have small seed, that other birds can't easily swoop and steal while being guarded by chix, and both high in protein.
Not sure if you eat meat, but they also don't really like smelling one of their own being slow smoked.
High - vis deer line is a scam. Deer are blue green colorblind, like some humans. Stringing pinecones on a fishing line works fine. High vis, is so people don't walk into them. The idea of a high strung wire, is deer have poor depth perception and will sometimes not take the risk of jumping, because they cannot gauge the hight due to the fine focus required to look at the wire, making the foreground bury and even harder to judge. Think aperture on a camera. Or try to look at the lines on your hand, and the room beyond your hand at the same time.
