Sherry,
Some questions need to be asked to limit down possiblities, without a necrospy on one and full pathology work up it will be almost impossible to say for sure, but there are sometimes that clutches fail to thrive about or many are losts in one clutch and we can try to rule out some of those
How old was the mother? Babies from mothers over 7 years seem to start having a higher die off rate and problems.
Have you cleaned anything that is plastic or resin based, inculding silicon in the tanks with bleach water.this is something that has happened in several clutches the past few years when they seemed healthy otherwise and we think the bleach heating up under the light may have a toxic effect on the babies. We recommend all items that have to be bleached, to siak at least 24 totally submerged and then air dry another 24 hours. Better yet, used a proven safe cleaner like nolvasan
How old were the first babies when they started being ill or dying? Viral infections usually run in cycles of 10 days to 2 weeks, many virus are shed by the mother when she lays egg, live on the shells and infect the babies either through the pourous eggs or when they hatch and walk on the shell (which way is not know for sure yet)
Crickets or food, can be a vector for many bacterias and some molds that can cause mycosis in the liver, they crickets get this from the feed they are fed on, most notable is corn grains that mold with a very violent reacting mold, the circkets are immune to any problem from it, but the reptiles it is deadly too.
Labs will accept crickets for analysis, I know that IDEXX will and some have come back with really poor results, one test showed 4 types of gram negative bacteria, 2 gram positive and 1 mold fungus........ those crickets would have been toxic over a period of time fed to reptiles, especially small babies.
I can not mention who the bad results were from, there were 2 companies (we can not show clear line of "evidence"
, but I can tell you 3 others we checked that were clear and healthy, Armstrongs Crickets, Timberline and Reptilefood.com
