I feel your pain. I have 4 salmon faverolles and i have had to use the broody breaker 7 times now in the past 8 months. They are just a year and a half. What a pain. I have 6 buffs that are 13 weeks old. If they are less broody im giving my faverolles away. They are not only broody but LOUD. My buff orpingtons barely make any noise at all.
Both of my Favs go broody several times a year. Supposedly winter layers, nope. Occasionally get an egg in the low end of USDA Medium, usually USDA Small. Low production. And they are also loud. Once they get going a number of the other birds start in as well. Not the favorites of my flock.
