They will not flee if they are engaging in melee combat with an adversary. Passive animals will mostly flee when harmed. Incest is common and has no effect on animal health. Animals that can lay unfertilized eggs can similarly afford a higher female ratio. On the contrary, animals that can be milked will want more females than this ratio suggests, as the gains from milk will offset the losses from time spent not pregnant. However, as the randomness involved with mating becomes more significant with smaller population sizes, slightly more males will be desired for smaller populations. As the proportion of time spent awake can be approximated to be about 2/3 for a rest effectiveness of 0.8, and mate_mtb is usually 12 hours, this can be simplified to 2/3×gestation_time or 4/3×egg_interval in most cases. If there was no randomness involved in mating, the female:male ratio that would achieve this is given by awake_proportion×gestation_time/(2×mate_mtb) for gestational animals, or awake_proportion×egg_interval/mate_mtb for egg-laying animals. In order to maximize the rate of offspring for a given population size of adults, the ideal is that the moment one female becomes pregnant or fertilized, another gives birth or lays an egg and becomes available to be mated. The female then has a 50% chance to become pregnant in the case of gestational animals, or a 100% chance to become fertilized in the case of egg-laying animals. The female will stand there, allowing the male to mate with her. In rare cases, more than one male can mate with the same female at once. Female animals do not ever attempt to initiate mating themselves.
