Our fabulous brown eggs are from chickens pastured on our certified Biodynamic pastures. We grind our own organic custom mix of chicken ration to supplement their diet of bugs & grass & scraps from our own vegetable production. We procure the organic grains from other Nebraska farmers that certify organic. We sell our eggs direct on-farm year-round, as well as through Open Harvest in Lincoln. We are at Old Cheney Farmer’s Market in Lincoln from late April through earliest July. Certified organic eggs means they receive no antibiotics, hormones or GMO grains. We rotate the chicken houses throughout our pastures in moveable houses with portable fencing to protect them from wild animals & neighborhood dogs, as well as protect the produce from the chickens. They are an important part of our pest control management strategy (chickens love grasshoppers especially!) & forage makes up about 30 percent of their diet. We pack our eggs nest run -- this means mixed sizes in a carton. Carton weight total runs from medium (minimally) usually hedging towards large. The chickens are an important part of our farm rotation, providing pest control, increasing fertility, working in a balance with the produce, cattle & hogs.
