I've boutght and fed off approx. 30K crickets per year. I just get my next supply and they seem ok. It seems overnite I get a mass die off approx. half of my 4K I bought for the next few weeks. Such a wonderful stink...YUCCH! Any suggestions as to why one day fine the next mass die off. I've kept them the same in a large plastic tub fed the same food Ive fed others that last 2-3 weeks on. Now I'm ticked off and suffering from stinky dead crickets.....
