What is the Size diff Between bantam Sumatras and Standard ?

[barngem]

We have Sumatras that are 4 mo old going on 5 I am wondering if they are close to being full grown. Our Roo is getting a beautiful tail so I am going to assume he is about grown but he does not crow? This will sound dumb but do they crow? Our Old English Bantam started crowing at 3 weeks old. I dont care if he doesnt I am mostly wondering about size. Someone else ordered them for us an the info said the hens would be 4-5 lb and the roo 6-7lb I have to assume that is bantam size. Maybe not. Any one know?

Those weight are correct for Large Fowl Sumatras. Bantam would be much smaller.

Here is a picture of my Bantam Sumatras:

You can see how tiny they are compared to that quart jar that held their water.
