Spain’s national police are in the midst of an animal abuse investigation after 26,000 live baby chickens were found abandoned at the Adolfo Suárez Madrid-Barajas Airport earlier this week.

About 23,000 of those chicks have since died, police confirmed.

In a news release issued by Spain’s Policia Nacional, officials were first made aware of the shipment of chicks three days after they arrived at the Madrid airport, where they were being stored in a cargo area. The cardboard boxes holding the chicks had been damaged due to rain, which had stalled the next leg of their journey.

By the time police were made aware, approximately 6,000 chicks had already died due to starvation and cold weather, and the remaining — some of whom were eating the dead chicks to stave off hunger — “were dying.”

“The putrefaction of the dead animals caused a strong odor that further increased the poor conditions of those still living,” wrote the police, in a translated statement from the news release.

Police added that the company that produced the chicks had put them into the care of a shipping company, who neglected to care for the animals, according to the original company.

Two different animal protection organizations were called to transport and care for the remaining live chicks, although about 3,000 more were too sick and died. Now, only around 3,000 of the chicks remain alive. As CBS News noted, they are now in the care of the two animal protection organizations.

One of the organizations, the Asociación para la Liberación y el Bienestar Animal (ALBA), wrote on Facebook that the “ the culprits of this disaster will be held accountable.”

The organization further said that the chicks will be available for adoption after they recover, but only to “families that don’t use them for consumption and give them a worthy life.
