problem with the rooster population is that roosters will
fight each other to the death for chickens and territory.
Humans take advantage of this and have illigal cock fights
where roosters fight to the death so that people can make
some money. This is absolute cruelty to animals and many
governments and peoples are trying to stop it. But apparently
it makes a good show for crazed gambling men and women."
When a rooster has a "favorite" hen, he will mate with her
all the time and ignore the others. In this case you can
either keep the rooster separated from the hens for part
of the time, or you can keep his favorite hen separated
for part of the time to see if he spreads his attentions
a little more evenly when she is gone. Young roosters calm
down when they get their wattles rubbed, or if they are
given a raisin treat.
