Mares are made to give birth to only one foal at a time. Rarely a mare will deliver twin foals that are able to survive, but this is truly a rarity.

The number varies depending on the species and the conditions at the time of gestation. A very common species, eisenia fetida, usually has around 4 offspring per cocoon.
If eastern cougars did not have offspring, they would become extinct. They have one or two at a time.
as many as 18 eggs at a time. It takes about a month for the chicks to hatch.
Lions have fewer offspring compared to fish because they invest more time and resources in raising each offspring. Lions give birth to only a few cubs at a time and care for them extensively, whereas fish produce hundreds or even thousands of eggs at once with little to no parental care, relying on the sheer number of offspring to increase their chances of survival.
From 1-10 is normal.
Overproduction refers to the phenomenon where individuals in a species produce more offspring than the environment can support. This can lead to competition for resources among the offspring, as not all will survive to adulthood. It plays a crucial role in natural selection, as those with advantageous traits are more likely to survive and reproduce, leading to evolutionary changes over time. Ultimately, overproduction contributes to the diversity of traits within a population.
