Gold partridge Brahma help

[JenWillo]

So I had been convinced that my 5 GP brahmas are all boys but I’ve read on another post that males get black chest feathers. Also my light Brahma boys have little pink combs by the same age as these guys and no sign yet. What do people think?

Solid feathers on the chest for Patridge patterns do indicate male, yes.
