A long-legged Marans would look much like a Langshan to me. The body feathering can make legs appear longer or shorter. I don't worry about white wingtips, they always molt out. Toe or tail feathers that are white...that's another thing, more serious to me.Any comments about short vs long legs, especially on the roosters?
I don't really get a sense for that when I read the Marans club standards (didn't look carefully?), but it seems like the illustrations show a big bird with short legs.
I really like the look of a longer leg with the overall proportions of the Marans rooster.
On another note, any comments about white wing tips as chicks feather in?
