If you took a look in my Kitchen Compost Crock, no matter what day of the week it was, you'd probably find coffee grinds (with the filters) and egg shells. In fact you could even rename my crock, the coffee grind and egg shell holder and that would be okay with me.
These are the ingredients that get me going in the morning and these are also the ingredients that get my compost pile going.
Now you've probably heard people say that you should never put meat or fats in your compost bin because they'll attract little critters and I agree with that. But I know some people who actually wash their egg shells before adding them to their compost. In my opinion, those people are crazy people.
I just toss mine in there and I'm done. Most of the time, I'll bury the crock contents under some leaves to keep the yard looking neat. But this time I wanted to get a few pictures first.
