We have not been able to identify this breed of rooster that came with our run of buff orpington hens. He is currently 17 weeks old. His tail feathers are coming in as a deep emerald green color with a touch of cream and brown. The rust/brown coloring is symmetrical on both sides. Ignore the red coloring on the very end of his tail feathers - he brushed up against wet paint when we painted the coop. Possibly Silver Leghorn? Columbian Wyandotte? We can't find anything yet that matches. Thanks for any help!
