I plan on incubating my first eggs soon. I am hoping to be able to afford some breeder-stock, show quality eggs. What vaccinations and medications should I absolutely buy in the very beginning? And what are some common meds that I will most-likely need for raising chickens on a regular basis? What company is the best to buy from? We raised champion field-trial dogs for many years and, provided them with some supplements. Because we started supplementing in the middle of our dog-raising years, we saw visible benefits in our dogs almost immediately. Is there supplements that provided obvious beneficial effects on y'alls birds? Please explain? Please?
