I suggest giving each their own space/crate, toys, food, water etc. Give Baci everything first. First attention, first new toy, first food, first treat. Give them time to get acquainted. They will tell you when it is time for cohabitation. I had two ex-pens in my living room during this time and it was not long before I caught them cuddling together and knew the time was right. Just don't force them on each other and let Baci know he is still #1.
