Yemayá told Olokun that she raised some animals that he would enjoy eating. Olokun answered that he also raised one that she would like: the rooster. Until then Yemayá tasted nothing but hen, and Olokun fed only on abó and eledé.
Later Yemayá went to Olokun's dwelling to show him her flock. In the yard, Olokun saw that they were ducks and that they could not stay upright: every time a male stepped on a female while walking, they all fell. He became angry and declared that those animals were sick, because he fed only on strong blood.
Yemayá burst into tears of sadness at that remark. Olokun invited her to take a walk, and on the way Elegba met them and, on seeing Yemayá's tears, began to sing.
The two followed a path, got lost and returned without meaning to the place where the ducks were. There they saw, astonished, that all of them were swimming with ease. Olokun praised how beautiful they looked. Yemayá chose several and offered them to him as unyén.
Elegba remarked that it was a very appetizing dish. Olokun invited them to go to his own flock, where he raised rams, pigs and roosters. He gave them some of those animals to taste and wanted to know which they liked best; both chose the rooster. Olokun said he wanted to give them something different, to see whether they liked that too, and came back with two geese. On seeing them, Yemayá and Elegba fled in terror. In the flight they threw up the ram and the pig they had just eaten, and so they came before Orunmila.
He consulted the osode for them and saw Ofún Batrúpon. He said that they had eaten three things and that two of them had made them ill; so they had to offer an ebbó of rooster and duck, with a basin, sea water, nine candles and blue and white cloth.
Yemayá ran to look for the duck. Elegba obtained the rooster by theft from Olokun's flock, and the two of them put the ebbó together. Orunmila prepared it and ordered it to be taken at nightfall. Inside the basin he sacrificed the rooster and the duck, and the whole ebbó was taken to the sea. At dawn Olokun discovered something very beautiful floating on the water and was very glad.
From that day he fed the roosters well and, behind Yemayá's back, the ducks too, to give them strength. Then he summoned Yemayá and Elegba, and ruled that Elegba should go every day to eat rooster and bring some to Yemayá, and that she should send him ducks.
Thus, in this path, the vigor of the duck and the rooster was born, birds of weak nature. From that moment Yemayá feeds on akukó and Olokun on large, sturdy ducks.
