Hi!
You didn't say how old Zoey is, but I'm assuming she's young. Yorkies ears 'generally' don't stand up until 3 or 4 months. They can go up and down many times before they stay up permanently. Teething will also make them flop back down, for a time. You can trim the excess hair off her tips to help lighten the load, but if she's under 4 months of age, I personally, wouldn't worry about it too much.
Please post pictures after you get her home. We all love to see puppy pictures.
