This is very racist. I have never heard such a children song. Where did you find this?

As Gokuyum said,  it is racist, meaningless thing that was made up by some racist minded people who tried to spead it among childeren. I heard that unfortunately, I remember when I was child, some kids were singing this thing and it sounded fun to us in those times  but now we realize  how evil it was to spread such things among children and washing little brains with hatred against other nations.

I hope there is no child still remembering this song.

i have never ever heard that before. what is the source for this?

We have many racist stuff but i dont care about rare, personal, unknown things. A random person can write such a nonsence thing and thousands start to discuss...

I only know this children song including numbers and it is very innocent

Mini mini birler
Çalışkan ikiler
Tembel üçler
Dayak yiyen dörtler
Misafirdir beşler
Altılar altınımı çaldılar
Yediler yemeğimi yediler
Sekizler seksek olup gittiler
Dokuzlar doktor olup çıktılar
Onlar kırmızı donlar
