Really can't help ya for sure, but................ A couple years ago I tried some kernal guard. Its smelly and a P.I.A. to deal with, but the gophers sure made a mess of the neighbors corn right up next to mine. The tube sensors did not like it either. I think its close to a buck or buck and a half an acre. Can't remember if you have the CCS? It might be worth trying it in the outside 3-4 rows to border the feilds. Might work for birds? If anything the smell would keep em away! Just a thought. Maybe someone else has more info on this? Good Luck | 
What to do about pheasants eating our corn????!!!!
