It's funny, how
we get concerned about a balanced feedstock for our worms, sometimes more than our own diets. (I am not saying this without including myself in the "we"

) If your worms are keeping up, then I think your balance is going well. You will notice an imbalance when the bin becomes more favorable to other creatures in your bin, and
their numbers increase. Observation is one of the best keys to what goes on in your bin. Mostly you will just be doing what the rest of us are doing...Standing over our bins, scratching our heads, and then coming here to share information and observations.
