Pros: AWESOME layer, curious, friendly
Cons: can't think of any
I started with four pullets last summer (an Australorp, an ISA Brown, a Silver Laced Wyandotte, and a Barred Rock), in July, right around the age they should have started to lay. The Australorp is bright eyed, inquisitive, friendly, and best of all, is an awesome layer. She was the first to start laying (I thought that the ISA would start first, but she was actually a few WEEKS behind the Australorp!), and has layed nearly every single day since. The only time she stopped was for about three weeks around Christmas, when a neighbor dog bypassed three fences, two gates, and a barn door (he was determined) and ate my Barred Rock, right out of the barn, in front of the Australorp (and incidentally, my ten year old daughter, who was out gathering eggs). Within a few weeks she had started again, though, and hasn't stopped since!
