All my birds are adults, can they still use the chick grit? It's pulverized like sand, would it benefit the big girls, if not, can I still use it for something? Dang.
It'll do them some good as grit, but not as good as hen-sized grit. You could use it if you wanted.
Or, it is quite good for 'sanding' icy spots on the sidewalk or driveway or whatever, if you ever do that sort of thing -- doesn't melt uselessly into the ice the way darker colored sand or gravel do.
I got a BIG bag of it too. Good idea for the driveway, we're getting a lot of snow lately! thanks Pat. I'll put it in their dishes and see if they munch it.
