Reishit HaGez is the giving to the Kohen the first cuttings of the fleece of sheep grown in the Land of Israel (based on Deut. 18:4: “You are to give them the first fruits of your grain, new wine and olive oil, and the first wool from the shearing of your sheep.”).
Most Jews cannot perform the mitzvah of giving Reishit HaGez (wool shearings) to a Kohen because they don’t own sheep. The same is true with regards to giving the zeroa, lechayayim and keiva (foreleg, cheeks and stomach) to a Kohen.
But this guy got himself a sheep and went shearing on a farm in Nebi Samuel in the hills near Jerusalem on May 28, 2015.
