I looked in on my lobster roaches today to find a female giving birth. Right at her abdomen, having a nice snack, was a subadult nymph! Of course I swatted him off, by my question is, was he feeding on the newborns or the afterbirth produced by the female? There were easily 5 or 6 freshly molted nymphs of various sizes sitting in the enclosure nearby, so I'm thinking the thief wasn't actually after his relatives.
