Dominique chickens love to forage, and like to scratch and forage for as much of their own food as possible. Commercial chicken feed that is of high quality is also recommended to help supplement their dietary needs when they don’t eat enough when foraging.
The Jersey Giant chicken is a bird that loves to forage, which means the best type of food for them is the bugs, grass, and seeds they get from foraging. You will, however, need to supplement their foraging with high grade chicken feed. You can also feed them healthy table scraps from your kitchen.
