When I grew up I got really friendly w/ a couple guys that ran a pet store in my hometown and after going there w/ my mom I was cleared by her to quit my paper route and become a permanent fixture at the store after school. The petstore used to deal w/ reptiles, amphibians, tropical and saltwater fish. I remember learning the fine art of raising crickets from my buddy Gene. Now at that point I'd been keeping reptiles for half my life and making my weekly pilgrimage to the pet shop and buying my weekly stock of food for my animals.
I remember telling Gene... "This is a lot of work raising these things. Why don't we just order them?" (At the time I used to help w/ the ordering and I'd see 1000ct, 5000ct, 10,000ct etc. on the crix). He told me that they used to and it was always hit and miss. The crix would either come in mostly in tact or they'd have mass casualties. It was more efficient to raise them in house for our customers. Now this was back in probably like 1989-1990 ish... Sounds to me like the cricket industry hasn't changed all that much in the last 18 years or so.
If I were you I'd salvage what you can from this order and start breeding your own. After I learned how to breed crix, I did it for at least 8 years until I switched over to roaches. I had great success w/ them. It's a lot of work (by my standards anyway) but if you don't mind it than you won't have to go through this aggravation any more.
BTW I am going to defend MOST of the cricket farmers out there, not all of them... Just MOST of them. Crickets aren't that hardy of a feeder anyway, so shipping them can be a real pain in the butt. They just drop dead for no apparent reason. I know that a lot of these companies put just as much care and effort into shipping their product as any other feeder company out there. The odds have just always been stacked against them. They've always taken a constant beating on the complaint lines and I gotta give them props for having thick enough skin to deal w/ that. No way in hell would I want to be in their shoes. They can have the cricket industry.
