Tried it.
Sweated, cried, have blocked out the mental anguish.
Of branches falling and taking whole sections down. Of sticks catching in one area only for the wind to help another area catch on too, twisting to create a gordion knot that can't be undone with a saints patience, adding weight that drags down into a handy funnel for all manner of smaller detritus to gather in a bowl of bird's nest pickings.
Laboriously untangled upside down cockerels legs out of it. Boys who thought barriers must be challenged and logic be damned.
Untangled said cockerels in the deep dusk of "why isn't he in bed yet, where is he?"... Unanswered by the hens of course.
Needed desperately to pee while untangling the other cockerel with family requesting I hurry up for dinner.
Umm... Where was I?
Okay, don't do it. If you value your sanity and dry pants.
Around trees, one could string independent lengths of rope. From different directions, most in the obvious angles of approach. This works on the "too scary to fly through there" principle inherent in hunting birds who are cautious of injury that could interfere with gathering snacks.
If a net it must be, something with larger diameter holes, like a volleyball net, that can allow the majority of tree flesh and reproductive products to fall through.
Some keepers on here profess appreciation for a specific brand of net with wide holes and strong string.
It has a name.
I do not recall it (see what net trauma has done to me?).
There may be people on here who may know its name.
When I was trying to craft a username, I couldn't think of something that fit me. What kept springing to mind was, "A rose by any other name would still smell as sweet." It was really annoying. Then I caught myself thinking, "But I'm not sweet, I'm sour." ... Thus my username.
Roses have thorns. You know what else has thorns? Invasive weeds that grow up and into your netting and continually poke you while you're trapped within your own net handiwork needing to pee with an upside down cockerel with 16 strands of net wrapped around his leg and he's trying to beat you with his wings because he thinks he can gain lift from upside down and people are yelling at you due to their hungry stomachs and is it really your fault that chickens go to bed about the same time many people imbibe sustenance?
