I bought these as day old chicks. Supposed to be speckled sussex. I thought I had indentified them as Welsummers when I had four dark eggs and only three Marans. I've since figured out that these two mystery pullets are not laying the extra dark eggs. (I guess there was a Maran egg I missed). These girls are laying basic medium brown eggs. Do you think they are black sex links? They have a lot of gold to them, though. Ideas? Thank you.
