We have pheasants as well. I sow parsnips and cover with rows of potting compost in nice neat black stripes and they come and tossed it about the place. I thought they ate the seeds, but they all come up but not in straight rows. So they do not seem to do any damage. Certainly do not eat broccoli. Plenty of weeds so not sure they are eating enough of those either.
Actually the netting does nothing for the deer, they can just move it or chew a hole in it. It is a major problem if it snows so the PSB is the only thing sticking out of it.
