Seams like a good idea never tried it my self do you find it hard to close it up with hay all over the ground around the feeders? after putting a few bales in them in the same spot I seam to lose the bottom of the ring feeder in 6 inches of rejected feed and find my self pulling it up which can get very difficult if there is rejected and spoiled feed left at the bottom of the feederIf you use 3 sections, you can take one out and close it up when they've eaten the outside. If I'm feeding bales out with ring feeders (which I don't often) then I use 2x 3 section rings, so that the 2 'spare' sections can be pinned together when I take them out.
