I thought Cochin's were supposed to have a docile temperament like silkies, but my Cochin cockerel (he's at breeding age) is kind of an a-hole. He charges at me and pecks at other birds. He's really beautiful, but I don't want a mean bird. The other three pullet Cochin's aren't as bad, but still are a bit pecky and not so friendly. Did I get a bad batch or are Cochin's not so nice?
