It is illegal to dye a baby chick or duckling.

The Law Explained

In the past, vendors would dye baby poultry in pastel colors to sell as festive Easter novelties. This law was passed to prevent animal cruelty, as the dyeing process and subsequent impulse purchases often led to the animals' poor treatment or death. Fortunately, naturally yellow chicks are cute enough. Today, the law remains a firm stance against using live animals as holiday decorations.
