To Fifth Street Mama: This is an interesting puzzle..Number 1 looks like a Columbian Wyandotte and Number 2 a Light Brahma(Can't be sure because legs are partially obscured), Number 3 "No Clue", Number 4 the real puzzler: Almost certainly NOT a Barred Rock because of feather pattern and legs; Cream Legbar would be a guess especially if the hatchery hatches this breed...Hope someone can give a definitive answer that seems right to you..Best Always..
