Chicken Size Chart

The breed chart below is meant as a general guide ONLY due to the tremendous amount of variation in size and shape within a breed. To measure the length, you must make sure the tail and neck are fully upright. Measure from the base (bottom) of the back of the neck to the base (bottom) of the front of the tail.
