I had a medium square tubberware like bowl to feed my chickens with. It worked well but I was filling it up ALL the time and sometimes they would run out before I got home or would dump it upside down. This didn't happen frequently but I wanted a new feeder anyway. (I love to shop for chicken supplies. ) SO I bought one, it is a red plastic one that is huge and looks like a bucket. You pull the lid off, fill it up, and put the lid back on as the feed falls out the bottom of the bucket into the lowered pan below. Works wonderful as I am not filling up a bowl every five minutes. Now, the problem was I realized I was going through a lot of feed but I figured having only to fill it up so little and it holding so much that it wasn't as bad as I thought. This whole time, including the time I had a bowl I had it on a cement block, well when this occured I added a cement topper to the block. You know, like the thinner pieces that is supposed to cover the holes in the blocks? So you can get an idea how tall this thing is. It is pretty much even with their backs if I had to take a guess. I thought this was good but I am still using way to much feed. To give you an idea, I filled the whole thing up yesterday and today I am a little below half. Wouldn't you say that is a little much? I do have to admit that there is some pellets around the area to attest to the fact that it does get spilled, don't know how but it does, but it sure couldn't be THAT much. I don't know but I hate to waste so much feed. I don't mind if I know they are eating it and are healthy but if it's going to waste... Thanks for listening to me ramble and for any help or replies.
