I have looked at tons of photos, but yes agree mine look like this. I wonder who trying to crow.So im really only good at over-analyzing pics, but it works for me!! I was comparing yours to the started pullets... they sure look the same.

One of my girls here.. omg.. i need to record her attempt at crowing, sounds like she's calling the pigs home! (Don't worry, no plans for a pet house piggy)
