That is surprising that you have had such poor performance out of your Salmon Faverolles! My SF hen is 1 year old and has so far laid an egg 6 days a week even through the winter months. She hasn't had her first molt yet, and has never displayed any broody tendencies, but then again she is close to the bottom of the pecking order so maybe that factors in. She does indeed lay a small egg, but hers are the best overall for boiling and sturdiness compared to all my other breeds, so I still consider her to be an exceptional layer and beneficial member of the flock. I was simply listing the breeds I myself have had excellent success with in laying while pointing out the fact that no flock of hens is going to lay 7 days a week, 365 days per year without shortening their laying years and stressing their bodies.
