Wellll, don't give up on her just yet. SLW's are actually a terrific breed to keep. I have had at least one since I started keeping poultry, when I got my first own little farm. They are very low maintenance, are friendly, curious, not very noisy, don't fly well, can serve as layers or meat chickens, and seldom go broody. I currently have 10 in my own personal flock. I raise, and sell, other breeds, and can honestly say that when I have any Wyandottes for sale, they go quickly. You may read about them not doing well in heat, but our summers here in Central Florida feature 100+ days with jungle like humidity, and none of mine have ever suffered from this. All in all, they are easy to raise and keep chickens, with very friendly personalities and great with kids.
Enjoy your girl, and let me know when she lays her first egg!
