I dont think so. Leghorns have yellow legs, and white earlobes. It looks like yours has grey legs and red earlobes, from the picture, but it might just be the angle on the earlobes. Leghorns usually have huge combs too, and yours looks small.
Thank you both...I haven't had her for a whole day yet, so not sure what color her eggs are. If she's not a Leghorn, what other breeds could she be? Are there any telltale signs for those?
Not a leghorn. The have larger combs, white earlobes, are stark white and sleek looking. This bird looks like a mixed breed, maybe with some game or something like that.
