I'd like to inject something into this discussion. The mere fact that
hatchling maiasaurs *could* walk around does not mean that they *did*, at
least not much. The crushed eggshells and differently-sized babies are
evidence enough for me that the baby maiasaurs were hanging around the
nest, for a while at least, whereas the baby orodromes were not.
