The huge combs(the red fleshy bits on the heads) are very large and red. Which can be breed dependent but I'm sure they developed those pretty quickly.
The red one has a deeper red brown color on the shoulders which is male specific coloring. The darker barred one also has male specific coloring in the shoulders.
The crowing. The point shiny saddle (above the tail) and hackle feathers(around the neck)
These feathers are more coarse and and pointy. If you compare these parts to your pullet I'm sure you'll see the difference.
The red feet is an indication of testosterone. But sometimes isn't visible depending on leg color.
Their size. Their upright stance, pullets tend to be lower or more level depending on the breed.
They also appear to be getting sickle tail feathers in which are longer feathers which continue to grow (especially in long tailed breeds) and are on the top edge of the tail usually. These feathers eventually grow quite long and curve. Like sickles.
This is not my photo and I hope this goes through
