Preheat oven to 400 degrees F (205 degrees C). Grease a baking sheet.
Whisk together the flour, sugar, baking powder, and salt in a large bowl. Using a pastry blender, cut in butter and lemon juice until evenly mixed and slightly crumbly.
Whisk together the eggs and half-and-half in a small bowl; add 3/4 teaspoons lemon zest with the egg mixture to flour mixture, and mix gently just until well blended and forming a dough. Fold in the huckleberries.
Divide dough in half, and on a floured surface, shape each half into a ball, then flatten slightly.
Cut each round into six wedges; place on prepared baking sheet.
Bake in the preheated oven until tops are golden brown, about 12 minutes.
Whisk together powdered sugar and lemon juice to make a glaze.
