Congrats. Like Alexa said, girls each have their own personalities, however I would not say they are any smarter
Reena is definately the queen of the roost, Shelby is more cautious, and Ruby is the life of the party. I love my girls!
The girls take a little more time to warm-up to people, maybe because they are mostly always in groups. Once seperated, they take a few days to get used to it, but when they do, they start to show their unique qualities.
