Zoomorphic pepper shaker slurry hen

Adorable set consisting of a salt shaker and a ceramic pepper tree representing chickens. They probably date from the 60s. They are in good condition, no cracks, the caps underneath are functional. Each had a small ginning of the enamelling on the tip of the tail, I made a small retouching (oil paint and a touch of varnish, I do not know if it will hold in time or washing, I am not professional in the field of ceramic restoration, see last photo for the aspect before retouching). They measure 7 cm in length, 4.5 in width, 6.5 cm in height (at the level of the ridge). The whole weighs about 80 g.
