Anyone have plans or ideas on how to build a trough feeder. I use gravity feeders now, but I can't figure out how to keep the deer pellets dry. I mixed oats in with corn and pellets last week. The oats are supposed to help with the moisture, but it doesn't look like it has worked. I have an idea how I think they should look, but some definate measurements would help alot. Any plans or ideas would be appreciated.
