Blue soda, Don't feed those crickets. They won't expell enough of the fungus/ick to be safe to feed and they will probably die in a couple days anyway. And, if your dragon eats them it can make him/her sick.
Who was the vendor you got the crickets from? Was it Ghann's Crickets? I got a Horrible order from them a little over a week ago! The box of 1,000 crickets arrived with almost all of the crickets alive, however, 2 days later I had mass die off! Over 300 deads! I removed the remaining live crickets, and a couple days pass, I come home from work and another mass die off of over 200 more! At this point I got rid of all the remaining live ones as well. The potatos in the box were fine, not moldy. And, I have a 10 gal viv with a screen lid. I put the crickets into the clean viv with a small,shallow bowl of water crystals, some carrot pieces (carrots don't rot like potatoes do, they shrivel) and a small bowl of cricket chow. By the way, this was my first, and only order from Ghann's and I've have never had a problem before with any other vendor I've ordered from. I sent Ghanns an email about the mass die off. The response I got back, of course was that it wasn't their fault, but due to shipping, weather, exhaust from the delivery vehicles, etc... and a copy of the guarantee, which is limited to live delivery, nothing else. I sent them another email stating that I was not expecting a refund or replacement, (but an apology, at the very least, would have been appreciated) and that I felt their crickets were unhealthy and would not risk feeding them to my dragons. I also let them know that, since they felt they were in NO WAY responsible for the mass die off, that this order was not only my first from them but would be my last and that I would not be recommending their website to any reptile owner that I know! I haven't received any other response from them, SO, apparently they are such a big company they feel they can afford to lose the business of 1 customer. Hate to remind them, but it's proven fact that 1 unhappy customer will tell an average of 12 other people about their bad experience where as 1 happy customer will tell an average of 5 others about a good experience! I figure I've told AT LEAST A DOZEN PEOPLE! So, basically I'm a little ticked (to say the least) and out almost $25.
