i have 1 female russian and 1 male russian. during the winter the male lives in the sulcata cage right now(i think its to cold for a sulcata to be outside) and the female lives in in the normal russian cage. they live together on cold days and at night time. during the summer one gets half of the day in the outside russian cage while the other stays inside for half the day, then i switch them. the female lays so many eggs, but they never hatch. the temps are at 86 and the humidity is at 66 when i incubate the eggs. is there something up with the male? why do you think they don't hatch?
