Dont 'roll it' onto the floor, it will make a big mess for sure! What I do is that I mix it with the kibble and save the shells. When I have enough I place them on a cookie sheet and bake them, then ground them into powder.
Also, as a side note, the farm fresh eggs are much better than the store bought eggs. I mainly give fresh eggs, since my grandmother has a lot of chickens, but since egg laying time is down I supplement a few times with the store bought eggs
