Is it possible that I recived Cornish X's instead of the Dark Cornish that I ordered? This is my first time ordering chicks though the mail and this morning I recived 16 very small, very yellow chicks. I looked at the picts. of the dark cornish chicks and they all seem brown. Will my chicks turn brown or did I end up with the wrong breed? I don't want Cornish X's - what should I do with them?
