Look for additional vendors. Cost for me is ~$135 per 164 foot length. My coons are every bit as tough as`yours and more numerous yet they do not defeat the netting. Limitation you will have is protecting an acre then it is recommended only four lengths per series to limit fire risk.
How many birds are you trying to protect.
That guy was the cheapest. $200-something for the net, another $200 for the power source, then 15% tax on top of that. Ordering from the states would wind up about the same after shipping and import fees. Number of birds fluctuates - right now I'm down to only 11, 3 of which are near-future chicken dinners. I've had as many as 40 when u count/include the babies.
