Warm up the milk. Sift the flour into a bowl. Press a depression in the middle. Crumble the yeast and mix with 100 ml milk. Dust with some flour from the edge. Cover and leave to rise in a warm place for about 20 minutes. Melt the fat in the remaining milk
Add eggs, sugar, salt, vanillin sugar and milk-fat mixture to the pre-dough and knead to a smooth yeast dough. Cover the dough and let it rise for another 30 minutes. Roll out the dough on a floured work surface to a thickness of approx. 2 cm. Use motif cutters to cut out roosters and chicken. Put the motifs on 3 baking trays covered with baking paper.
Mix egg yolk and cream and brush the motifs with it. Decorate with sugar crystals (eyes) and almond slivers (feathers). Bake the trays one after the other in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for about 15 minutes. Let them cool down on a cake rack. Cut small "combs" from strawberry slices and put them into the yeast buns
