What on earth is this?!

The ? light sussex chick with the head dot now looks like this http://i22.photobucket.com/albums/b345/tomcat1/Chicks009.jpg at just over 2 weeks old.

I don't think s/he is a light sussex any more but I am foxed if I know quite what s/he is. I hatched it out of a mix of eggs sold as light sussex, white maran, silver maran and light sussex x rir (google seems to suggest these should all be reddish brown?) from ebay, but the seller has previously sold Speckled sussex, red Mottled leghorn, white wyandotte bantams, gold laced wyandotte, red/black yokohama bantam, Dark Brahma and old english marans.

I'd say a Delaware, as our hatched chicks looked very similar to that. But Delawares are pretty rare, I'm not quite sure if you're breeder would have them. Are there spots on the head? That's a good indicator if it's a Delaware.

EDIT
I read your post again. So it does have head spots. Could you post a picture of the chick standing on it's own? I can compare the whole body this way.

theres and image or a slightly older pullet but you can see the white colored body with the more yellowed head. Also the black along the tail and wings.

EDIT
and here is a picture of one at 3 weeks.

again very similar.

Delawares are excellent layers just so you know. ;] It's good luck for you to have wander up this little one. As I said, they are quite rare. They have wonderful personalities as well, and are very kind, loving chickens.
