Yes, as a treat apples are fine for chickens. Some will say it is best not to feed them too many apples as the seed of an apple has a small amount of arsenic in it. I have an orchard on my property and in the fall, the chickens run there first thing in the morning. Never had a chicken drop dead under an apple tree.
Chickens also eat less exciting foods, like vegetables, fruits, flowers and grass. They eat grains and seeds. They scratch the ground and find bugs and specks of things that we canât see. So, the question isnât really what chickens eat, but what the right diet is for them. In the 19th century most chickens were barnyard scavengers. They hatched out under their mamas and were taught to look for grain in the horse stalls, and for bugs and greens in the garden.
