Thank you for explaining that. The one with black on her tail and neck feathers looks so much like my Calico Princess, but from what I've learned, Calico Princess have barred feathers (my girl does but just on her legs). She is a high egg production which makes me nervous knowing what I know...
My Calico Princess started at 17 weeks and my Barred Rock started at 18 weeks. Not sure about my others, (SLWyandotte's, Buff Orpington and another Barred Rock) but everyone was laying by 26 weeks
