Our first hatch in many years is coming up next week and I got to thinking about vaccinations. I know you can get hatchery chicks vaccinated, but what about your own hatchlings? Is it necessary/desirable?? I haven't seen any discussion about it, so am assuming hatchery chicks are exposed to lots more viruses, etc. though when our girls free range they run straight for the bird feeder, so are probably exposed to all sorts of wild bird diseases. What are your opinions about medicated feed? I'm doing a test hatch this time, but have some expensive eggs coming in a little bit from hither and yon and don't want to screw it up!
