Hi Matt, I ordered a pound of Euro's and a pound of Red Wigglers from you and they arrived in great condition and very healthy.  My bin is an opaque blue 22 gallon sterlite bin consisting of newpaper, corrugated cardboard, and dried up leaves.  Everything was moistened to the dampness of a "wet sponge".  After a few days of letting the worms adjust to their new home, I fed them.  They didn't seem to be eating the food at all.  I should note that the bin was set up 2 weeks prior to the worms arriving and was jump started using Bonide's compost maker (ingredients: ocean kelp, fish and alfalfa meal).  I then added some fresh grass clippings....BAD IDEA!!!  After a day, I checked on the worms and the wigglers were loving the fresh grass.  The euro's however were in trouble!!!!  I noticed they were very lethargic and some of the worms were dying.  Others were still barely alive and looked really deformed.  I did a little research and the deformities they showed were exactly the same as the "string of pearls" mentioned around the internet.  Also, the bin was teeming with fast moving white and brown mites along with their slow moving white cousins.  The worms were also doing everything they could to "jump ship" lol.  To make a long story short, I removed all the grass and food scraps I could and added tons of new bedding, some lime, and some diatomaceous earth.  After a couple weeks, the bin has settled down and things are great now.  It also resolved the mite issues.   I guess my question here is, what caused the string of pearls to start with???  Was it the acids from the grass composting or was it the gases produced from the uncomposted food scraps exploding the little guys insides???  There doesn't seem to be a whole lot of info about this on the net.  Any help you could give me on how to avoid this in the future???  I'm sure someone else on here has had to have had this happen to them...
