I have not found an effective bird/critter deterrent other than netting the trees. I have an idea to build a "rodent breeding structure" in the field with a release mechanism incorporated into it. I FIGger if I can release, or better yet, catapult an X (pick one: mouse, rat, rabbit, etc.) from the structures on a regular basis, the birds of prey that eat the road kill in the area might become a permanent overhead fixture. They can keep everything away from the fruit.
I have seen the video before. Unfortunately, there are only two major sources of shredded trees in the area. One is the Bartlett Electric Cooperative, but they give theirs to a not for profit boys/girls group in Killeen and the city of Georgetown who used theirs to feed the free mulch program they have. I called the private tree service near me (not too many) and found only one who was willing to dump. He's only called me 3 times this year, twice he wanted to dump unshredded bushes and once I was out of town when he called. Realistically, I need about 600 yards initially for 6" deep and over 200 yards/year to add 2" to the field.
