Only female goats, known as does, give birth. Male goats, known as bucks or billies, cannot give birth. Therefore, the number of goats that give birth corresponds to the number of pregnant does in a given population.
While it's impossible to provide a specific number without knowing the population size of does, we can understand that only does are capable of giving birth. They typically give birth to one to four kids, with the number increasing as the doe matures and has subsequent pregnancies.
