Today I went and bought an Aylesbury duck to live with my pekin duck, she appears quite small and her feathers are not in great condition ( very muddy ) I’m so glad I got her as I don’t think she was treated very well in her previous home. One thing I noticed as soon as I let her in the run was that she made a high squealing type noise. I wondered if I should b worried about this. She’s eaten and drank lots and lots.
