  2. Place your selections on the chart within the column marked Beak for: (A few of the identical beaks could also be discovered on completely different birds).
  3. Study the photographs of every chook and decide the kind of toes every chook accommodates.
  4. Place the identify of the chook on the road that greatest describes their kind of toes.
  5. Additionally place the foot kind on the chart in column 3 titled Toes for. (Some foot sorts could include multiple chook.)
