I have Saxony, welsh Harlequin, blue Swedish & 2 Rouen mix.
My Saxony is by far the most inquisitive. My WH is a scardy cat & the lowest in the pecking order.
My Blue Swedish is in the middle of inquisitive but cautious.
My Rouen mixes especially the female are loud mouths & are always telling me off it seems.
As far as laying goes. My Rouen mix female never missed a day until she just stopped laying for the winter break. The other 3 took turns taking a day off here & there & stopped before my Rouen mix stopped.
