I voted skids because they are easier to move around. Put enough angle on them to stabilize.

Skids with some method of putting down t-posts or rebar to prevent hogs or cattle from moving them.

I voted skids, but I gotta say, I like the legs an awful lot. 'Guess 'cause the pictures remind me of the lunar lander. I watched it live, you know.

With skids, wouldn't you end up with some corn under the feeder that the deer could not get to?

I'll go answer C, offer both. Legs for the base price, skids for a $25 or $50 upcharge.

I really like the fact that your legs are removable and this is one of the first ones I've seen where that is clearly viable. It also makes it look much easier to move around and install in the field by a single person. For skids, maybe pre-welded left hand and right hand sides that attach with the bolts you have in the picture. Plus crossbeams that would run from the left to the right using a similar bolting approach. Since the legs bolt on, I would probably build the entire thing on it's side or upside down and then tilt it over. So cross bracing would be a must.

It will be the other way around, legs is more fab time and materials.

If skids would allow you to hook it to your 4 wheeler or UTV to move it then skids...but otherwise, legs.

Skids with holes in them for tying them down. Looks like a good design.
