Do you have a Royal Purple male? If so, and you have one that shows at least little bronzing on his wings that would be my choice to match up with your Bronze Hen.
Sometimes The Guinea Farm in Iowa sells adult birds... but I don't think they ship adult birds and only allow local pick ups. Another breeder to contact would be Shady Hollow Farms, they are in Maine. Not sure where you are located.
No eggs right now from my flocks. My Hens usually stop laying mid or late Sept... after a couple months of 100+ degree temps. The males no longer bother breeding and the Hens decide to give up on laying eggs because it's just too miserably hot. My 1st timer pullets start laying in early January tho, with the older Hens kicking it into gear a month or 2 later, so I still have a decently long laying season.
Do you find that the eggs you get from a guineas first laying season are fertile and hatch out healthy keets? I would think so....maybe....or do they need more time to mate frequently/reliably?
I need to hatch something!
