venturing into Ts

so i've decided to try my hands on cricket breeding. I put the heat lamp right over the soil and the temp is reading 75 at the soil plate. Will the youngster hatch at this degree? If i always have fresh food for them inside the tank do i still have to remove the adults so it doesn't eat the pinheads or the eggs? I sometimes see males digging around inside the soil plate, are they digging up and eating the eggs thats been deposit by the females??????

On another note, my smaller P.regalis shedded, starting to show blue! but too small to photograph properly so I took a photo of his gf instead (i hope its a girl)
