I am adopting 3 black star hens this week and don't know much about the breed. Also I have 6 other chickens 3 are Auracaunas, 1 cochin, 1 bantam all hens and 1 orpington rooster. They are all about 3 months old and I was wondering if these black stars (3 year olds) will hurt my little ones? The bantam esspecially is quite small and really gentel. Will they all get along?
