Zolotoy tsyplyonok (1981)

Chicken Ryaba beared the egg, but not simple, as it happens in fairy tales, but gold. Knowing about this greedy Fox is forcing the Wolf to steal Ryaba from Grandfather and Baba. However, the Wolf manages to carry away only the golden egg. From it the dreamy Fox hopes to sit out a new chicken carrying golden eggs. She forces the Wolf to incubate the egg, so he lies for a long time and heats it.
