I am wondering if anyone has used an extra large range feeder that holds 300+ lbs of feed in the south. I want one for our flock of 60 which would allow me to purchase and fill it with feed once a month. My husband is concerned the moisture would ruin the feed and/or maggotts & bugs issue would result. Any experience would be appreciated. I am trying to simplify on some of the chores and this is a large one. Right now I have 2 - 30 lb feeders I refill daily to keep them full at all times.
