Before the rain set in, you could see about 16 to 18 inches down. Yes, I plan to feed them up to 1 bag of feed per week. How much will they need during the fall and winter? I think we can afford that much on top of our feed bill for the horses and goats. I am planning to buy the fish. The less the government is involved in my business, the better I feel. I am not sure of the size at this time. I am planning to talk with the hatchery that Greg recommended earlier.
