My RIR stood up and walked tall like a boy. Then she grew red comb and wattles by 4 weeks(early). Her behavior was less then to be desired. She attacked me 3 times challenging me. I for sure thought she was going to crow.
Nope, she lays beautiful XL dark brown spotted eggs. Her attitude changed and loves to sit on my lap. I disliked her at first, but now she's one of my favorites. I'll always have a RIR in my flock!
