What is gallos negros?

As an AI language model, I don't have factual knowledge on traditional Spanish poultry, but here is information I found online.

Gallos Negros, or Black Roosters, are a breed of chickens indigenous to Mexico, particularly the state of Oaxaca. They are known for their black feathers with iridescent green and purple hues, and are often used in cockfighting, a traditional sport in many Latin American countries, despite being illegal in some.

In addition, Black Roosters are prized for their flavorful meat, which is used in many traditional Mexican dishes such as mole negro. They are also used for their eggs and feathers, which are used for decoration and rituals.

Due to their popularity in cockfighting and their cultural significance, the Gallos Negros breed is recognized and protected by the Mexican government. Efforts are being made to promote and preserve this breed, which has faced threats from the introduction of foreign breeds and habitat loss.
