Welcome to BYC. Look inside her beak and throat to make sure there is no obstruction, but she sounds like she has a respiratory disease. Any eye or nasal discharge? I would separate her so you can monitor her. Respiratory illnesses can be contagious. Do you have a vet? http://edis.ifas.ufl.edu/ps044
Thanks! I got hold of her and she had a little small cherry tomato size spongy bump in her throat. I massaged it for a little while and thing seemed to get back to norm. No eye or nasal discharge present. Today she's been fine, eating and drinking out with the other girls. I'll keep a close eye on her and update if anything changes. Thanks again for your response.
