Well, we made some updates to the barrel feeder! First - Greg fixed it so it attaches more securely to the post. We didn't use big enough washers on the inside the first time. This time he got some large (1.25") washers which should be much better. We used 2 - 4" lag bolts to the post in the loafing shed. It seems really secure and so far seems to be holding up well.
I changed the netting out on the bottom. The horses had worn a large hole in the original hay bag and after doing a couple of repairs with twine, I decided they needed to work harder to get their hay! I "unstitched" the original small mesh hay bag and replaced it with some smaller mesh netting - shrimp netting with 1" spaces.
Well, after a week, I've only had to fill it 3 times - the horses are definitely having to work harder to fill it, but they can get the hay out. I'll be watching them over the next month or so and see how it goes and how well the netting holds up. So far, so good......
