Gen-san's free-range eggs. 20 eggs in M-2L size (2 packs of 10 eggs each) will be shipped in a cardboard box. We ship freshly laid, morning-harvested eggs on the day of shipment, so they are fresh. We are committed to animal welfare and raise our chickens in a free-range environment with as little stress as possible. Egg characteristics: These are eggs from the Boris Brown breed of chicken. These eggs are reddish-brown, and the whites are high and rise, and the yolks are firm and do not easily break even when picked up with chopsticks. They are also called the king of red eggs. They are popular for their rich flavor, depth, and delicious taste. About the feed: For drinking water, we use fresh groundwater (water quality tested). We are particular about domestic, additive-free feed, and we mix and ferment rice, wheat, rice bran, soybeans, oyster shells, fish meal, etc., ourselves. Especially fish meal is an important nutrient that affects the taste of the eggs, so we use fresh, additive-free bonito fish meal made to order and sourced from Kyushu. While it is generally made from the scraps of farmed fish, we use a high-quality product made only from bonito. It has no fishy smell and tastes delicious. In addition to this feed, we give them a lot of vegetables and green feed that we grow ourselves, which are natural green grasses. Green feed contains a lot of natural vitamins and fiber, which has the effect of keeping the body slightly alkaline, making them less likely to get sick and grow strong. My chickens do not have their beaks trimmed, so they can peck at hard things like potatoes and pumpkins, which are given during the winter when green feed is scarce. They especially love pumpkins and bamboo shoots. *Note: We do not give any antibiotics, vaccines, or other drugs for disease prevention or treatment, so you can eat them with peace of mind. We follow the livestock breeding hygiene manual and have received high marks in audits by the livestock hygiene inspection center. About washing eggs: The eggshell is protected by a membrane called the cuticle layer, which guards against the entry of bacteria. We recommend washing the eggs just before eating them. Expiration date: (Autumn and winter) 21 days How to use: Please consume raw eggs within the expiration date. Eggs that have passed the expiration date or have cracked shells should be cooked thoroughly as soon as possible. *Note: Beak trimming is a very cruel and short-sighted act of cutting off the tips of the beaks of chicks shortly after birth to prevent them from pecking and killing other chickens due to stress or lack of fiber. Unfortunately, nearly 90% of domestic laying hens undergo this procedure.
