More than being fed, they are looking for salt. Many years ago a group of us hiking in the mountains east of Santa Fe and stopping for lunch were approached by a small number of young female big horns. If you had a sweaty sweatshirt off for drying in the sun, or a sweaty daypack off they would taste then try to chew it for the salt. If offered something salty, they would take it. They didn’t intimidate us but scared my black lab who cowered in fear.
I have been hiking in the mountains near Albuquerque, Santa Fe and Taos many times.
