[ThiefPouter06]

WHat are the differances in these three colors(if any)? Is it just differant names in differant breeds?

This is one of the cases of hobby names.
BBR, I believe, in US, is usually taken to mean e+, wild type, duckwing & sometimes called partridge.
BBR is a silly name to be given for birds of one particular e-allele, as the males of many of the e-alleles could just as easily be described as black breasted reds.

Partridge can sometimes refer to e+ birds such as in the partridge Welsumer the name is also used to refer to eb birds with pattern gene (gold concentric pencilling) such as the 'partridge' wyandotte, cochin etc.

Brown is the name often given to birds with the e-allele eb.

 

[Sonoran Silkies]

Brown is also used to refer to e+ birds such as light brown dutch or leghorns. Or E^R birds with gold as in brown red.
