A shelter in Mexico near the United States border is housing not only migrants and asylum seekers but also chickens, pigs, and possibly fish.Asylum seekers are forced to wait out their U.S. immigration cases in Mexico.They often spend months at the San Matias shelter run by Rev. Hector Trejo.The shelter is in the large industrial city of Ciudad Juárez, Mexico.It is across the border from El Paso, Texas.The wait is stressful for people who in some cases are fleeing painful situations in their home countries.And the costs of feeding them have also been growing.Raising their own food appears to help with both difficulties.Trejo said, "On one side you have a space with the possibility of producing food; on the other, you have a safe and decent space for the families so they can go through their process in the most harmonious way possible."The shelter keeps pigs in an area where migrants can stop by to rub their big noses.It also has vegetables in a greenhouse to protect them from the cold winter temperatures.
