White leghorn? The pullets/hens have big combs. Too bad about the first egg, but I don't eat the first few anyway. The hen is still practicing sometimes, and doesn't always get it right.
Congrats on having a very pretty girl!
Oh! I just looked at your location! Be sure you protect that big comb during the winter, they are very vulnerable to frostbite. Keep her warm, and when she's out and about a liberal coating of Vaseline will help. But do keep an eye on it!
