ID:	724 this sac was fertile and i got 183 spiderslings from it, this female then made a second sac that was not any good (partly down to me i think) so i though she was now due a molt as she looked haggard but when i got home from being away she was in the middle of making sac number 3, the third sac was infertile and she later ate it.
Three eggsacs from one mating i thought was very good its just a shame they did not all hatch out.
Anyway thanks for reading.
