Any chance the suspected rooster could be a lady?? I’ll be so sad to have to re-home them.
I think there is a chance of two females, but I'm not entirely sure.
It's hard when the age is unknown like this.
Neither one has male saddle feathers (long, narrow feathers on the back, that hang down to each side of the tail.) That could mean they are females, or it could just mean one or both are males too young to grow those feathers yet.
Since there has been no crowing, that could mean females, or it could mean young males.
No eggs could happen with young females, or not-laying females of any age, or males.
So I see a whole bunch of maybes here.
Since they were fully feathered when you got them, and you've had them for 3 weeks, then you should be able to know within a month or two-- that would make them definitely old enough to crow and grow saddle feathers, or probably old enough to lay eggs.
My initial thought too! I don’t think I’ve ever even seen a Jersey Giant before - how much do they tend to weigh when they start laying?
I haven't seen one in person either.
The official standard weight is 10 pounds for a mature hen, but hatchery birds would probably be lighter than that, and pullets start laying before they reach the mature weight, so maybe as low as 5 pounds or so?
