Only the same number of people as think you need a cockerel for the hens to lay eggs.
It takes a crane to build a crane
It takes two floors to make a story
It takes an egg to make a hen
It takes a hen to make an egg
There is no end to what I'm saying[member=150944]DeterminedStudent[/member], I'm sure you know you'll need a cockerel before you can hatch chicks, and if you don't already have one, they're not difficult or expensive to get hold of. Just beware that random cross-breeds won't sell for very much money (even a point-of-lay commercial hen (ISA brown etc) is only worth about £10). So if you fancy breeding a few, there's nothing to stop you. Just start out with your eyes open, and know that this isn't a road to riches, or we'd all be doing it!
