"Get the portable ultrasound—now!" Dr. Evans commanded. Ben sprinted to her truck, grabbed the unit, and set it up with trembling hands. Dr. Evans coated the probe in gel and pressed it against Felicia's flank. The screen flickered to life, casting a ghostly green glow across the stall walls. On the monitor, Dr. Evans gasped as the image came into focus.
Felicia wasn't carrying one foal—she was carrying twins. Worse, both fetuses were wedged tightly together in a dangerous breech position, locking the birth canal. But as Dr. Evans zoomed in on their bone structure, her jaw dropped.
"Ben, look at the jawlines and ears," Dr. Evans whispered in disbelief, her hands trembling. "These aren't horse foals at all. They're mules. Whoever bred her didn't use elite stallion semen—they used cheap donkey semen." Without another word, Dr. Evans pulled out her phone and dialed 911.
