I got ten Silver Laced Wyandottes from Murray McMurray Hatchery - They're on the second post in my blog (link is in my signature) They all turned out females, and to my judgement, they're the hardiest of all the breeds I got from Murray McMurray. All my other breeds from them had some sort of casualty or another. Some even had 100% mortality rate. As for looks - They're not too bad. The only downside to mine were the tails being too long and high set, and the lacing on a couple being too partial. Otherwise, after 6 months of age their personalities settle well and their egg laying is fantastic. Most of them have very good coloring.
The photos on my blog are of them at 5 months, though. I'll get some new ones tomorrow. It takes about 5 plus months for the lacing to settle into the adultly feathers. At a young age you really aren't sure as to how the lacing will turn out.
