I agree with the general meaning of the phrase ("wasting time on unserious business"), but are you talking about the way young kids like chasing doves on the streets, stomping to make them to fly away?
If you are, I don't think it's the case here. Maybe it's not important, but I want to elaborate.
"Голубей гоняют" as a part of their training process (I'm talking about domestic pigeons, of course). I don't know the specifics, but for
(better: to) a casual observer it looks like a person runs back and forth on the roof, whistling and screaming
andwhile pigeons are circling above.
Amateur pigeon breeding was VERY popular in Russia and Soviet Union in the early/mid 20th century - maybe till
the 1960s. Many boys and young people had pigeons at the time, it was a widespread hobby, and you can stumble upon mentions of that in different Soviet books/films/songs. Moreover, this hobby often was not approved by adults, because kids often enga
ged in semi-criminal activity because of
[s:2rpj8vbb]that[/s:2rpj8vbb]it in order to get money to buy pedigreed pigeons, making bets, etc. It was a kind of "street kids" activity.
BTW, if you saw "Ghost Dog: The Way of the Samurai" you could see how Ghost Dog "гоняет голубей" (just for a few seconds, though).
