What I won't do is buy from back yard breeders who have no idea @ all about the genetics, & take no care or thought for anything but making a quick buck.
I hadn’t really thought about that when I was searching for my Faverolles. Where I ended up getting them from looked liked a good set-up; they were on an actual property rather than just in a suburb and they seemed genuine about being good breeders. They had other breeds as well, they were all kept separate and each breed had their own free-range day so there is no cross-breeding. My friend, the Frizzle breeder is putting a lot of care and effort into her purebred lines, and I know it would have taken her years to get to this point.
My first flock were mostly rescues ~ ISA browns past their egg laying best but all I knew was they were being given a reprieve from the butcher & the pens. I'd never heard of reproductive issues. Now I won't touch them because I am much better informed.
Me too, I am of the same opinion. Although, as I said to @Shadrach , if some rescues materialised and needed a home, I would take them in but I won’t actively buy ex-battery hens again. It’s definitely too heart-breaking (and expensive! $5.00 chickens? Pah!)
