Whole grain eggs are free-range eggs. The differences between whole grain eggs and ordinary eggs are: different sources and different chickens.

1. Different sources

1. Local eggs: Local eggs come from free-range chickens in the natural environment of farmers.

2. Ordinary eggs: Ordinary eggs come from uniformly artificially raised factory chickens.

2. Different chickens

1. Local eggs: Chickens that produce local eggs eat whole grains and forage freely during the day. The chickens grow naturally without external factors.

2. Ordinary eggs: The chickens that produce ordinary eggs eat organic feed and are fed uniformly. The chickens grow under the influence of external factors.

Local eggs:

In the true sense, mountain eggs, grass eggs, and wood eggs are other names for local eggs. They all belong to the local egg system. Of course, there are subtle differences between them: pheasant eggs and firewood eggs are almost the same concept, specifically referring to eggs produced in mountainous and hilly areas.

Local chickens are fed with sorghum, sweet potatoes, corn, potatoes, taro, yams and other coarse grains. Native eggs and grass eggs are almost the same concept, specifically referring to eggs produced in plains and lakeside areas. Local chickens are fed with rice, wheat, peanuts, soybeans, mung beans, fruits and vegetables and other coarse grains. These are all natural, pollution-free eggs.
