Lot of 7 chicken/rooster/duck miniature figurines, small collectibles

This is lot of miniature figurines featuring chickens, roosters and a duck. The chickens are made of a painted cast clay or ceramic material. One is marked Stafford Collection, the rest are not marked.  The duck is made of metal (perhaps bronze or iron) and is heavy for its size. Pieces measure 1-2 inches. Unsure of age but likely vintage. In good pre-owned condition with minor paint loss to several pieces.
