Well, I always think they should sleep inside. Little Yorkies are not meant to sleep outside IMO.
One day, a friend of mine came over, and got Lucy and Ringo to playing. They did so well with her and that is when I realized their problems were jealousy over me. They had nothing invested with her . . so were able to play with her without being jealous of one another.
I would keep them separate inside for a while using baby gates or some such. That's what we did at first . so everyone could have their own space . . and get used to each other's smell, etc. without being close enough to get into a fight.
