My 2 year old female has laid 12 eggs so far. So far about 5 have gone bad. Ok, that's fine. But i have several (from what I can tell) viable eggs that have been incubating at 83 degrees. I use hatchrite as a substrate. After 11 weeks incubating, my first and second clutch began to dent. ok, no big deal, they are getting ready to hatch. then low and behold, mold begins to form. I gently wiped off the mold with a q-tip. they are still in the incubator, but have become darker in color and look pretty sad. I bred this female last year to the same male as this year and had a 100% hatch rate. I can't figure out the difference between last year and this year. the only thing i can think of is that maybe the hatchrite is too old? Does hatchrite go bad? I bought it for last year's breeding season and have been using the left over. Please help..

As far as using vermiculite, do you use albey's method still? and do you think that i should switch all my eggs to vermiculite or use vermiculite on eggs in the future. I have three eggs going bad and 4 more that still look good. I'd hate to lose them all!
