THey are likely to be infertile, but you never know. Take them out of the cage and put them in a covered container with moist perlite (you can get perlite at a garden store. Be sure it doesn't have any additives like fertilizer. Put it some place where the temperatures won't go below about 72 degrees or so (better experts can correct me on temperatures if I've got it wrong). They will take at least 11 weeks to hatch. Keep them till they either hatch or stink.
