I have a Reptibator. My two females, now five years old have laid 105 eggs and not one has hatched. The incubator is set at 82 degrees and the humidity is 70-90 percent. The eggs are half buried in damp vermiculite. I think my male is shooting blanks. Also, how long do beardies breed? When are they too old? I have a huge custom enclosure, but the male still annoys my girls. One of them has a top pedigree from Fire and Ice and is a dull gray despite perfect temps and bright lighting. Also, how long can I expect my beardies to live?
