Our Austra White is nearly two years old, and lays 5x weekly, when not molting. She only took a month off for that, during which time she also survived a hawk attack. We have had severe flooding, severe drought, temps above 110, temps below zero, ice storms, hail, snow, strong wind gusts -- she's not bothered by any of it. She actually loves snow, and willingly walks out into a big snowy patch to just stand and gloat about her amazing camoflauge. Beautiful temperament with people and other poultry and has been one of the friendliest birds since she came to us as a day-old chick.
She loves to jump on our backs and snuggle up on our shoulders, and is easy to handle when caring for her. Example: when I came to find her after the hawk attack, she was hiding under her coop. I crouched down and scootched in to see if I could gently reach her, but she came right over to me and waited to be picked up. She loves to hang out with me during chicken chores, though sometimes gets chased off by my Barred Rock (who is also an amazingly tough, lovely, and easy to handle hen).
