A foal is now being raised by two mums after a "one in a million" birthing phenomenon left a mother without a foal to care for.br br Sol, now just one week old, is being cared for by Mary and Starr, both six years old, after one of the donkeys gave birth to a stillborn foal.br br Both mothers gave birth at the same time and both attached to the healthy foal.br br Farm owner Ben Best, 32, believes the chances of his two pregnant donkeys giving birth early and at the same time "must be one in a million."br br Mary and Starr were expected to give birth in June, so neither donkey was set up in the birthing barn.br br Since they foaled more than a month early, they weren't being monitored, so no one at the farm knows which donkey is the biological mother.br br Now, the pair shares parental duties equally with Sol feeding from both donkeys.
