This is how I would do it), I would tie the number of paws to the price of one duck!), for example, one paw - 2 cents, one duck, 2 paws - 4 cents, 3 paws - 6 cents, 4 paws - 8 cents, and 5 paws - 0.10usdt!!! but let them fly like before!!! both simple and tasteful! the price of one duck can be changed, think well!
