Though one of my EE cockerels at 4 weeks from a couple years ago had pullet like coloring for awhile until his breasts got filled in with dark blue plumage at 5 months.They are not sex-linked, no. A female specific pattern refers to the even distribution of pattern and/or color on the plumage. Males will not have even patterns over their whole body, nor will they have that light salmon breast.
Interesting! That comb sure was pronounced though.Though one of my EE cockerels at 4 weeks from a couple years ago had pullet like coloring for awhile until his breasts got filled in with dark blue plumage at 5 months.
Seems like I don't have a picture of the adult plumage of this boy anymore.View attachment 3310860
Red JungleFowl, both genders have salmon breasts, until the males molt it out. Salmon breasts on males lasts about a week, or two. Pictures I have aren't great.
I'm just using these as examples of how sexing isn't always straight forward.
I agree those are all pullets.
Comb, & a splotch of red on each wings were the only clues with him, besides early saddle feathers.Interesting! That comb sure was pronounced though.
