In the full Agni Purana this is chapter 232, verse 28.
Playing with herons, pigeons and mynas, he should say death. With tears in its eyes and licking at the foot with its tongue, it is for ruin.
Simple meaning: A horse playing with herons, pigeons or mynas points to death. Tears and foot-licking point to ruin.
वामपादेन च तथा विलिखंश्च वसुंधराम् ।
A horse scratching the ground with its left foot, sleeping on its left side or by day, is not good.
भयाय स्यात्सकृन्मूत्री तथा निद्राविलाननः ।
A horse passing urine once or looking sleepy brings fear. Refusing to be mounted is also bad.
यात्राविघातमाचष्टे वामपार्श्वं तथा स्पृशन् ।
A horse refusing a rider or touching its left side spoils the trip. Neighing at the enemy brings victory.
