Jason,
There is a lot of space for them in 5 acres and you just haven't connected with them yet. I think what I might try is to moisten it to saturation and the squeeze it in your hand to compress enough air out that it sinks. This way it wont be blown away or to the edges. Do this in the spot that you want to feed them regularly from. It's scent will attract them once they swim close enough as they make their rounds. After about a week try throwing some feed in the same spot to see if they will take it floating. Your feed might be a little big for 6" fish. It might help to break it up a bit until they grow a little bigger.
Are you planning to stock BG for the LMB?
