I intend to increase the genetic diversity of my flock, so I plan to go around town and buy some fertile eggs from local farmers/breeders/keepers. My main concern, and the reason why I am posting, is that I fear I might bring diseases to my flock. So the question is, does anyone know if there are diseases, that can be transmitted from the progenitor to the chick via the egg? If so, is there a way to prevent it? (like washing the eggs with a specific chemical..) Thank you very much, and merry Xmas to everyone!
