Grit

I noticed that there were bits of undigested corn in the chicken waste, so yesterday afternoon I added 1/2 of a large coffee can of grit to each range feeder. After some initial hesitation at the feeder, the birds started consuming the grit. This morning I noticed that it had all been consumed. I used both large and small grit which I had purchased at Southern States. Before I had only used the small grit. I also put in a handful of oyster shell grit normally used for the layers. If there is any undigested feed in the waste, then feed conversion is being compromised.
