I just discovered the Indiana BYC site on Facebook! If you have FB and get a second, I posted (slightly blurry) photos of my sons 5 SLW's. First pic is the straight comb possible roo!
I got 5 straight run SLW and one has a single comb. Bought them from the local Rural King (Cackle Hatchery is their supplier) We believe of is a roo so we'll most likely rehome him once he's older to someone who wants him as a pet. Son can't show him at 4-H :-(
