would a cockeral be necessary for chickens?
The man on the next lottie to me has chickens. He only keeps them for the eggs, so got rid of his cockrel, as he was making the girls very nervous. He says they are doing much better now, without him harassing them.
If you want milk from goats then they will have to have a billy (or a 'liason' with a billy) so they can have a kid. No baby = no milk!
I can also give you the address of an interesting Anglo/French Forum that we found invaluable for all those questions that keep you awake at night before you move!
