Sheryl Butler has some really nice showgirls. I like them better when they are heterozygous for the NN gene and therefore have a little fluff under the chin still (usually) and a 'bowtie'. Showgirl on showgirl is not my favorite.
Sheryl also has some pretty nice buff showgirls.
I have a blue showgirl hen I like a lot, she is tiny, has decent type, dark skin, large crest, large dark expressive eyes, is a fantastic layer for a silkie (I consider them a variety of silkie as they are shown as an AOV of silkie), and she's quite heavy bodied for her size (like a little butterball turkey).
Sheryl stated to me that she gets much better fertility with the showgirls. I am certain that the outcross to turkens, although quite far back, has imparted some degree of hybrid vigor. I think they do tend to hatch better as well. My little blue is just a champ of a layer- I adore her.
Here is a white young showgirl from Sheryl.
VERY young blue (believed cockerel??) out of my blue hen
