I have two golden campines in my group of 8 'big girls'. They are 21 weeks old and are really cool chickens - loads of personality.
When they were really little, they were the most skittish of the chicks (the others are more heavier breeds - wyandottes and dominiques) so I thought they would be the shyest when grown, but that isn't the case. They are the first to come up to see what the chicken lady has brought them for treats, and are not shy at all.
As they got older, they were the first chickens to cluck. They 'talk' to themselves constantly. They aren't obnoxiously loud or anything, just like they keep a running commentary going under their breath all the time. It's pretty funny, especially since the other girls are mostly quiet.
They are also very quick to defend themselves - again, not in a negative way, but they will confront the dogs and have made sure they all know who is the boss (in case you were wondering, that would be the chickens...)
They are pretty too - I got my girls from Meyer.
All in all, I really like them - they are not agressive but assertive, and extremely curious and good-natured. Now, if they would just give me some eggs, I could say they were just perfect!
