Hi guys! We just purchased 5 more pullets and can't figure out what the 5th one is. We have an Australorp, Black Sex-link, Holland/Barred Rock, Orpingtons, Welsummers, Speckled Sussex and a mystery hen! She has a golden neck area and looks similar to a welsummer but is definitely not one. She is the girl in the front. Any ideas? Thanks!
