Většina dlouholetých chovatelů mřížkovaných krajt uvádí, že krajty svou snůšku zahřívají. Teď jsem se ale koukal na nějaká pozorovaní z přírody a tam to zase na druhou stranu tak jednoznačné není. Každopádně bych věřil spíš údajům ze zajetí, protože tam je, narozdíl od jiných druhů, poznatků více než z volné přírody.

Like all pythons, the Reticulated Python lays eggs. The mother surrounds her eggs for most of their incubation period of 55–105 days (Wall, 1926; Smith, 1943; Branch and Patterson, 1975; Ross and Marzec, 1990; Cox, 1991; Manthey and Grossman, 1997; Cox and others, 1998; Walls, 1998b; Malkmus and others, 2002; Ziegler, 2002; Zug and Ernst, 2004; Auliya, 2006), presumably protecting them from light, desiccation, and predators (and potentially having some ability to limit mold or the spread of mold to healthy eggs). One would expect higher temperatures to expedite incubation, but hard data on incubation temperature in the wild are lacking for B. reticulatus (Shine, 1988; Ross and Marzec, 1990; Murphy and Henderson, 1997). As the reported incubation times usually lack information on incubation temperature, the incubation times are very difficult to interpret. Unlike some other pythons, however, the brooding mother python apparently does not warm the eggs with shivering thermiogenesis (Wall, 1926; Vinegar and others, 1970; Honegger, 1970; La Panouse and Pellier, 1973; Cox, 1991; Walls, 1998b; Malkmus and others, 2002), though some observers have claimed that she does (Lederer, 1944 (equivocal); Hediger, 1968; Shine, 1985, 1988; Kluge, 1993). Apparently heat production, if it occurs, is minimal or contingent on specific conditions.
