Apparently, Nigeria soccer fans are accustomed to bringing live chickens to games for good luck.
And, sensing World Cup staff might have an issue with that, they asked Russian officials if their fowl friends could accompany them to matches of the Nigerian national team (also known as the Super Eagles).
Russian officials unsurprisingly said no. No chickens allowed.
"Fans from Nigeria asked if it's possible to go to the stadium with a chicken - it's their symbol. We told them that it is not possible," Andrei Ermak, Kaliningrad's minister of culture, told the Interfax News Agency.
If Nigeria fans want to take their chickens elsewhere in the city to root on their Super Eagles, that shouldn't be too much of a problem, Ermak added.
