I got rid of 15 of my birds only to a month later add multiple other breeds. BBS Ameraucanas, BBS Marans, Welsummers, and Rhodebars. And yes, I will be setting up breeding pens for themthese actually are quality stock and not hatchery stock. It was nice buying from a real breeder.
I have not bought from a hatchery except CornishXs. They are so sickly. Cannot fight anything off.
I bought my first silkies from a farm close to me but her silkies were not great quality. I purchased a new roo and a couple of good hens, sold off/traded the original hens and processed the rooster. Now I have some good stock and adorable chicks. Still cant bring myself to sell these chicks.
