I would try re-introducing them to each other outside. Addy is trying to protect her house and she is also scared so she is fear biting. I have never had a problem with the rescues if I put the new dog in an xpen outside and then let the gang come out and smell the new dog. Within minutes everyone is racing around the yard and I let the new one out and closely watch for any signs. After about 20 minutes of play then I let everyone in the house and it has been interesting to watch the dogs go into their pecking order and the older dogs telling the new one what they will or will not accept.
Good Luck.
