I, too, have raised Salmon Favs, LF and Bantams. They are the real sweeties in the poultry world and most of the time they get picked on bad by other breeds. They do get along with other breeds better than my Black Aussie girl. LOL. They get along with my Amercuana bantam girls.
The eggs I get from my bantam girls are variable from small to medium size. They are about a third smaller than the LF Favs. Terrific egg layers.
I have a flock of Salmon and Black Faverolles that originally came from Mike Stapish. Lovely black birds and sweet personality to boot. Only one Mahogany Fav bantam girl...more coming LOL. The strains are hardy and you as a breeder must cull hot and heavy when you are looking for specific traits, personalities and conformation and most importantly, fifth toe placements.
right now I got some LF Blue and Black Favs in the incubator along with the blue salmon Fav bantams...cant wait to see them hatch and hope to get some blues out of this lot. I am looking forward in getting some white and buff ones.
