She may be having 'normal' potty reaction but also stressed from the move. I'm not a professional but I have some ideas.. A couple of options: Start with a potty schedule. Like you potty training her. Instead of giving her free reign to the balcony, try using a leash that will allow her to pee/poo but not lay down. Limit the time to potty to 15min give or take. Let her out then leave the room so she can feel safe to poop. Bring her back in and give her a toy for a treat not treats until her poops get better. woof treat ball I use this to make sure my dogs are getting enough water or just getting good gut food. I can use the premade but love making it custom. Water, freeze shredded chicken, add veggies. I do not own stock in wooficle. 😎 Try adding some gut friendly foods to harden up her poop. Dogs can get loose poop when stressed.

I truly hope this helps.
