That was to feeding by dumping it straight on the ground. When the chickens wouldn't eat it from a trough.
They seem to have a small enough number of chickens in a large enough space and maybe have good enough drainage that it is working for them.
I wasn't saying bowls are better than troughs...
Mine knocked the stainless steel dog bowl over too. They didn't knock over the stoneware crock but I like the dog bowl better. I put weights (literally, weights from a weight bench) in the bottom of an ice cream bucket under the bowl.
But yeah, they dig in the dirt anyway.
