Mama June ... Daughter Chickadee Threatens ... Cut Me In, Or Else!!!

Mama June has been quite the cash cow recently ... which is why her daughter Chickadee is fighting for a cut in the action.

June has found a way to make a lot of money post "Honey Boo Boo" ... we're told it's in the 6 figures. She's scored cash from paparazzi shoots and made a bundle doing various TV interviews.

Now the tricky part ... we're told Chickadee feels entitled to some of the money because June's only claim to fame is the TLC show, of which Chickadee was a big part. Yes, it's a thin argument at best.

And our sources say June has told Chickadee to pound sand ... her money is her money.
