Everything is scary and new and she needs time to adjust. I would not try and handle her or force her to do anything right now. I would leave her somewhere quiet where she can see and hear your other duck but she can hide if she prefers. If she had a larger platic tote or cardboard box on it's side or dog crate with a towel over it like a cave that she could go in and out of so that she feels like she has a safe place to hide out it might help, and then she can venture out or just look around the corner when she feels ready. I agree that you should at least get her out from behind the dresser.
