thresher (traditionally 'freshers') week is a gathering of college/university students from the surrounding areas at local farms to sift through the threshings (hay/wheat that has been harvested) to separate out any small animals/rodents that might have been caught in that years harvest and killed to stop it spoiling when stored over winter.
traditionally as a token of appreciation the farmers would let the scholars keep any animals they found as meat was expensive and scarce especially for students (much like today).
