There is not much lately on American Bresse these days, so I decided to respond to this old thread. I was lucky to buy some White Bresse eggs on ebay directly from Greenfire Farms in 2013. Hatched 6 hens and 2 roosters, as of today still have a roo and 4 hens. They are all originals from Greenfire eggs. I recently hatched some pure Bresse and some Colored Dorking hens & Bresse roo cross, the cross shurly shows hybrid wigor, they are growing into large birds all white but their legs are white not blue and some has 5 toes after Dorking mothers. I am going to butcher some crossbred roosters soon, hoping for good Thangsgiving feast . Will keep all pure bresse hens and roosters for now for future line breeding.
Generally speaking after 2 years of keeping American White Bresse pure Greenfire line here are my thoughts. Easy going birds, rather tame not timid, not flighty, healthy and vigorous , inspite white color they are savvy with predators, I lost several Dorkings and Orps but not one Bresse to coons.
Good layers of creme or light beige large eggs, rather not broody, I estimate they lay about 250 eggs a year. Anyway they lay better and their eggs are larger than my Colored Dorkings eggs.
If their meat proves to stand out better than Dorkings meat which are much better meat birds than any of "dual purpose" American breeds I ever kept, I am going to keep Bresse exclusively as dual purpose breed, and drop Dorkings due to their excessive broodiness which could be an advantage for some chicken keepers, but I do not care much for broody hens.
