Possibly, but we've found that even the J feeders with lids still result in wet food when there's a bad storm. Misty rain is just as bad as a windy storm. Since we've been placing the feeders inside the pens like this, we hardly ever had wet food. The feeders hanging on the exterior perimeter always get wet.
Also, cutting the wire would weaken it and I want to keep our pasture pens as predator proof as possible. We do have some feeders that hang on the inside of the wire on the perimeter of the pen. They're a pain as they always get wet. This has worked really well for our pasture pens.
I eventually want to switch us over to feeding grains. To help reduce digging through for treats and waste, I need to have a feeder for the various types of grains. I will probably have to install a wooden bar on the divider wire wall and screw the feeders into that. Reducing waste is a huge deal for us. With the numbers of rabbits we want to run, food waste will add up quickly. Not to mention that we now have a bazillion sunflower plants trying to grow all over the front yard! lol
