I think she means that they are literally around the house, and not in the house. The parrot room is curious, though. That's probably another broken down vehicle Mo has rechristened to be something else other than a broken down vehicle.
As GOBUCKS speculated, I'm pretty sure she meant the chicken's running around inside her house.
With the parrots, remember, and I don't think Big Mo would let the parrots fly around outside.
It's got to be inside her house, where she's now got chicken shit all over the floor, on the seats of chairs, in the middle of the dining room table, all over the bed-sheets, on the couch and kitchen counters, maybe even on the bottom of her bathtub.
Chicken shit all over the place.
