Am I more likely to pick up disease through a breeder's flock? I'm guessing they are more exposed to the environment than a hatchery and more likely to pick something up. I am concerned because my sister brought Coccidiosis into her flock by bringing one of her friends chickens in. They both ordered their chicks together, but her friend's must have been exposed in her yard while on medicated feed and my sisters weren't. She lost quite a few chickens. If a breeder is just as safe, what do you look for as far as certifications, etc. Or are there any you consider very safe that you can list. We are looking to add some more bantams to our existing flock. Ours all came from hatcheries and I thought it might be nice to have more choices. Thanks for any help. I'm very new to this.
