after dealing with lots of wasted feed all over the brooder I tried an old pie pan, the little baby feeders from TSC fit nicely and I have not seen any more wasted feed on the floor. I added a rock on top of a mason jar lib to keep it in place. The pie pan catches all the waste for easy re-filling.
I did the same thing with the larger 7# TSC feeder by placing it inside a flower pot bottom pan slightly larger than the feeder bottom...the 3 & 4 week olds out in the coop quit wasting food too. the planter base catches 99% of the waste and I just dump it back in the top.
