4th Generation are rare! It is difficult or impossible to find Fourth-generation (F4) Olive Egger female chicks.  F4 means the 4th generation of cross breeding yielding a darker olive egg.  These girls will lay beautiful, medium to large darker olive eggs-some with speckles (shown in pictures) at a good clip, about 4 eggs/week in season! The hens have a lovely wheaten feather color and are very sweet and friendly-good for families.  These beauties are cold-hardy, have straight or pea combs and may or may not have feathered legs and cheek muffs. The color Wheaten does not breed true. 4 olive eggs/week. Please note, there is a very slight 1% chance of a brown egg.
