Thanks for the info. mine will be outside so I'll have winter slowdown for sure, but I have space for a huge colonyDon't think I can truthfully answer that Kassaundra that would give you much to calculate with... as there could be too many variables, but here are some direct answers.
I started with about 50 or so worms and about 100-150 worm eggs, that I had diligently gleaned from our outdoor compost pile during late Spring last year. So there was quite a bit of time when the worms were hatching out and growing to maturity rather than beginning with an actual measurable amount (ounces or pounds). I did keep the vermiculture tub in the utility room where it stays a constant 70 degrees F. so there was no slowdown of growth. I've only harvested the compost twice since beginning with about 19 gallons of prime 'black gold' worm castings, thus far.
Regardig worm harvesting to feed the chickens, I haven't really done that much because we've only had the chickens since mid April. I have doled out several small handfuls of worms for them on occasion as treats, but I feel like I want to do more rearing of the worm population prior to next Winter. I still count many new eggs in among the leaves and food scraps so the population is still on the grow. I have noticed that I seem to have millions (possibly exaggerated) of very small baby worms as well.
So I guess I'm still trying to play it by ear.... Good luck with your vermiculture!
