Subtle ammonia smell, and wacky worm behavior.
I've had some (1lb.) Eisenia hortensis in plastic bins (18gal. Sterilite totes) for just 2 days.
I made the bedding with coco coir and some prepared scraps, and some eggshells approx. a week before adding the worms. The first day seemed to go well. Of course, being my first experience, I checked in quite a bit.
I started noticing bits of coco on the insides like it had splashed there, but I didn't really think about it.
Later on the 2nd night, I noticed about 4 had left the system completely, there were a couple in the leachate bin, and maybe a dozen or so at the lid of the bin.
There was a faint odor of ammonia, so I immediately assumed it had something to do with the food. Being late, I quickly prepared more moist bedding (this time mixing it about 50% w/peatmoss) in another bin and placed it on top of the other to give the worms a place to go.
I spent the morning going through the bins and gathering up the worms. While I was doing this, I found that while there were many worms that tried to escape in what appeared to be random directions, I think the majority actually were relatively happy and feeding!
They seem to have a fondness for potato peel, even. This puzzles me a little.
Why were some driven away while others stayed?
I also couldn't find whatever was making the ammonia smell, Maybe the eggshells weren't washed well enough?
I can't see that it would be good for the worms in any case. I guess I just have 2 questions after all that... What could cause the ammonia smell? and Do you know why some of my worms wanted to run, while others seemed happy?
