I recently bought 16 chicks from a local agway and it was really easy to keep track of who was who when they were younger but it’s kind of hard now. We had originally purchased Rhode Island Blues, Astrolorps, olive eggers, and Easter eggers. This is lady bird I though she was a Rhode Island blue but she’s a lot lighter than the other blues and I recently saw a chicken called a sapphire gem that looks exactly like lady. Also is it possible that she’s an Easter egger of sorts? Also her head feathers have been getting progressively darker.
