Insects are an instinctive menu for many birds and other creatures. Cicadas, aphids, scale insects, worms, crickets, ants, and many other such creatures provide a treat for many birds.
Chickens love gobbling up grasshoppers and locusts. There isn't any concern about chickens eating grasshoppers or crickets, though, because both of them hold the same nutritional value.
The amino acids in grasshoppers are a huge boost for chickens especially, lysine, methionine, and cysteine.
Carotenoids exist in a great amount in grasshoppers. Carotenoids are a great source of vitamin A and contribute to the color and quality of the egg yolk.
