About a month ago I purchased 7 pullets. They were supposedly almost ready to lay, none of which have. When I purchased them it was a mix of different breeds (I think she purchased the 25 brown egg layers). One of the chickens is all white with a black colored hackle and a little dab of black on her tail feathers. She's a BIG girl, out weighs my Wyandottes and towers over them. She said it was a Columbian Wyandotte. Well, it looks like a columbian wyandotte, but her comb (which is still small) doesn't look like a rose comb, it looks like the comb on my red star. After looking at the breed pics, I think she could be a Light Sussex.?? Does anyone have any other ideas? What do you think she is. I will post a picture when I can, I know it's hard with just a description, but in the meantime any ideas?
