I only have 2 backyard chickens. For the first month I kept them in their run and I filled up their small feed bowl with pellets everyday. They finished it all everyday. Now I am letting them roam my whole yard (maybe 1,000 sq ft) of tall thick grass. Since I’ve let them roam my yard (2+ weeks now), they haven’t touched their pellet food. They still look/act healthy to me. They still each lay a delicious egg almost everyday. I see them roaming and eating fat earth worms constantly. Should I be worried about their diet? And healthy eggs?
