Lots of info to be gained on the net etc but basically a bird with plenty of character, easy to care for although they aint keen on the cold and damp so the Winter spent indoors is advised. They dont lay a massive amount of eggs but lay more than enough to hatch a good number. They are capable broodies but probably best to stick with around 6 eggs. I would expect them to be quite pugnacious around other birds. They dont require a lot of room to be healthy and happy.....A 3' x 3' hut will house a trio fine.
Price wise, it depends who you buy from......unfortunately there are far more bad birds
