Do you buy grit or do you use sand? Some chicken keepers have suggested just giving sand to mature birds. Grit is just another thing to spend $ on. The sand around here has little stones in it and I give it to my 13 wk. olds and they SEEM to be okay. They do foraging and I give them bits of fruit, oatmeal, and various greens by hand........... Is insoluble grit that necessary, or can't they get what they need from the dirt they dig, the sand I give, etc. I'd get grit if it was a clear 'DO IT'; but I don't think it's that clearly necessary. Of course, "the books" say, 'Give real grit', but...........they're supposed to toe the line if publicly publishing!!! I must admit that real grit (12.00 for 50 lbs. here in MA) would probably be the ideal thing for good digestion, and probably nutrient uptake, as a result. But would the 'ordinary foraging chicken' get on her own what we call 'insoluble grit'? I kinda doubt it. What do you all do?
