OK, my dh went to the hardware store this morning and bought "bird gravel." It's bigger than sand (between 1/16 and 1/8 inch) and turns out not to be just gravel: it also contains oyster shells and charcoal. I'm guessing it's not good for chicks, right? Can I give it to my hen?
Maybe I'll just get some play sand.
