I cannot find grit for sale around here! The farm stores sell oyster shell, all kinds of feed, but no grit. I am still looking, but I wonder how urgent this is. I did scoop up some of the small (pea or lentil size) peices of granite gravel from my driveway and gave that to them in their run, and have noticed that most has dissapeared, so I am assuming they are feeling like they need it. Soon I may just order some from mypetchicken.com if I cannot find any locally, but I hate to do that as I am sure the shipping will be a lot for something that really should be inexpensive. Does anyone have any other ideas?
