Dog or Rabbit Feeder for Chickens?

[jomoncon]

i was looking at my Mom's automatic dog feeder & thought something like this would be good for feeding the chickens, as well as holding a lot of food. My Mom has the 50 lb size, byt the 25 pound size might be better.

Then, after some Google searches, I also came up with this:

This one hold 42 ounces, and that's really not very much.

Has anyone used anything like these?

My local feed store ordered me a baby pig feeder that is alot like that and works well.

Why not just buy a feeder designed for chickens?

Chickens seem to like to eat together. One starts, and the others go "hey, that's a good idea! Let's eat, too!". The dog feeder and the rabbit feeder you're looking would make it hard for a flock of chickens to eat together that way. The round ones designed for chickens let multiple chickens eat at the same time.

I do use one of those "rabbit style" feeders for grit, though.
