Picking on each other after the move

Well I moved (over 1 appartment) last Saturday. All of a sudden Jordan seems to be picking on Maggie. It starts out like play, but then she usually ends up ears pinned back hissing at him. I can't figure out if he's picking on her or she is just being a drama queen. I've got a Feliway plug in going, but I wondering is this stress from the move or what else could be going on? Isaac has started picking on Levi, but this has been a problem for a while & usually ends when Levi runs away from Isaac. Jordan & Maggie concern me more because he's chasing her & not allowing her to get away. Any ideas/suggestions?

He's trying to get a jump on the new territory, claim it for his own, and you may have to keep her in another room where she feels safe for a while and has her own 'territory'. Then try to reintroduce them a few days or so later under supervision.

Cutting off the aggression ahead of time and keeping him busy with a toy he can claim his toy may help as well as possitive reassurance toward her from you will help her feel better and act less timid which he is taking advantage of........goodluck!
