Deleware hens or roosters

[Abold87]

When we bought these from a private seller we were told they were all hens. Today 1 started to crow loudly. I began to look up differences online and seen that someone said hens wont have barred stripping in the tail feathers. All mine have these. And from photos mine seem to have more color around necks then other hens? Opinions please

Cockerels.... you can clearly see the long pointy saddle and hackle feathers also. They're beautiful birds! I hope you can keep them

Of the birds pictured, I see cockerels. How many are pictured??
Also, I'm not sure on the barring thing... this is what I was looking for.
