I have been interested in Favorelles since I have wanted to have and keep chickens. The one thing that keeps being said is that thay are in general a less hardy breed. I live in Central NY where the winters can be brutal -10 to -30 degrees for weeks on end in January/February. Last year it was the worst. and summers that can have high 80's and 90's in August as the norm.
I truly love the Favorelle descriptions of temperament and I adore their little faces.
Does anyone know where I can get Fav's from a strong, prolific, hearty line? I really want these little ones.
Thank you for any help and infor you can give me.
I don't know who called them "less hardy" but that's not generally the case. They do better in cold weather than hot weather. I'm sure they will be fine in your climate.
Hens go broody when you don’t want them to… and won’t go broody when you do.
