I was suspecting the same. When I hold Sweety, and hold one of his/her sisters... Sweety is much more bulky and bigger and more muscular. I was doing some research on the Barred Rocks...turns out..the lighter in color, the more it is likely too be a roo. I let my son pick out some chicks when we first bought them..and he picked out Sweety because of how lightly colored it was. I am actually excited that Sweety might be a roo. I have no restrictions on roosters where I live and 1 acre of land that they are all free to roam on.
Novaleigh, it looks rooish to me but just a guess. Nice comb going there.
