Gen-san's free-range eggs. 60 eggs in M-2L size, 6 packs of 10 eggs each, shipped in a cardboard box. ※ The ratio of each size varies depending on the outside temperature, etc. Freshly laid, morning-harvested eggs are shipped on the same day. 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, with a high, well-defined white and a firm yolk that doesn't break easily when picked up with chopsticks. They are also known as the king of red eggs. They are highly praised for their rich, full-bodied flavor and delicious taste. About the feed: We use fresh groundwater (water quality tested) for drinking water. We are particular about using domestic, additive-free feed, and we mix our own feed with rice, wheat, potatoes, soybeans, oyster shells, fish meal, etc., and ferment it. Especially, fish meal is an important nutrient that affects the taste of the eggs, so we use fresh, additive-free, made-to-order bonito fish meal sourced from Kyushu. While it is common to use scraps from farmed fish, we use only bonito, which is a high-quality product. 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 is natural green grass. Green feed contains a lot of natural vitamins and dietary 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 ※Note, 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. ※ We do not administer any antibiotics, vaccines, or other medications 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: 21 days from the date of laying (winter). Eggs are shipped on the day they are laid. 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 tip of the beak of a newly hatched chick to prevent it from pecking and killing other chickens due to stress or lack of fiber. Unfortunately, 90% of domestic laying hens undergo this procedure.
