I bought this chicken a couple weeks ago, was told it was a hen but the wattles and comb seems to be getting bigger. I'm not sure the exact age but it was hatched this year. I'm guessing around 5 months old? It's a couple inches taller than my other hens that are probably pretty close to the same age. I was told this is an "Amber White" which is apparently a cross between a Rhode Island Red and a Rhode Island White.
