They certainly have their own personalities, even if they dont have names. We have decided which female we are going keep. She is the smaller of the 2 with the narrowest saddle. She is the friendliest of the trio but is also striking up quite a relationship with us. The male is scared of nearly everything, he comes around if you are with him long enough or he has the company of his sisters. The larger of the 2 females is extremely confident and rules the pen.
