a horse can get a taste for acorns and search for them while grazing.
It is fairly easy for a hungry horse to eat several pounds of acorns in a short period of which can leading to a fatal overdose.
Some horses seem more susceptible to acorn poisoning than others who have a higher tolerance of the toxins in acorns.
