Instructions
Make sure that you qualify to adopt a mustang from the BLM. The agency requires that applicants be 18 years or older, be free of animal-abuse convictions or any transgressions against the federal Wild Free-Roaming Horses and Burros Act and be able to provide the infrastructure and resources to properly take care of the horse.
Provide the required facilities. The BLM lays out specific guidelines for these, including a minimum space of 400 square feet for each adopted mustang, six-foot-high enclosures for adult horses until they are fence-broken and corrals built from pipes, poles or planks of at least 1.5-inch thickness.
Apply to the BLM for a mustang adoption once you're certain you qualify and can provide for the animal. Applications can be submitted by mail to the pertinent BLM office --- the one administering your particular region --- or through the online system.
Pay an adoption fee. As of 2010, the BLM set a minimum opening bid of $125 per single horse and $250 for a mare and foal pair. In a competitive-bidding situation, the ending price may be higher. As of 2010, you may adopt up to the four mustangs in a one-year period from the BLM, or apply for special permission to take on more.
Prepare yourself for the challenges of breaking and managing a formerly free-roaming mustang. Depending on the horse's disposition, you may have plenty of work cut out for you to earn the creature's trust and devotion. Keep in mind that these horses grew up in semi-arid wilderness, covering huge swaths of country and dealing with equine herd dynamics. It won't be an overnight transformation.
