In some parts of Africa, pink dye is used on domestic animals to mark ownership.
Most banknotes mark stolen banknotes with seemingly pink dye. This dye used on domestic animals especially Chickens includes a mix of pesticides to color the fangs of some animals.
This coloring and chemical composition make Ivory and Keratin unsaleable to most poachers as it is impossible to completely cleanse them of that substance.
Animals are not harmed in any way by these chemicals, however, thieves find it difficult to hide stolen animals.
Next time, when you see a Pink Chicken you know what it means.
In the wild conservationists mark animals with pink dye to throw blows on poachers.
