I am about to order 4 dozen or so different breed sexed chicks soon to jump start my new farm set-up. I was gonna start slow then grow, but have gotten too impatient, so will probably order all at once instead of 1 dozen at a time. I hope to get 1 doz. California grey & white, about a dozen RIR, 18 sex-linked, and 1 doz Ameraucana. I want a variety to decide which breeds I prefer and so I can have white, brown, and ee. Since these will be my 1st chickens, I need to be sure about what I should and shouldn't worry about as far as vaccines go. I have to be as careful as possible with cost (our budget is EXTREMELY tight), but I don't want to be so cheap that I end up paying for my impatience with hens lives. What diseases must be vaccinated for at birth and which can wait until I can do it myself? Are any recommended, but not a BIG worry? I know lots of people do rabies annually on goats, but I don't. I'm not worried because our babies are pretty safe from any risk of exposure. I don't mind doing anything I REALLY SHOULD do, but I don't want to spend a lot more than I need to. Like I said, since I'm spending more at the outset to get a quicker jump-start on my flock, I want to be sure to get any vaccines necessary to protect that investment, without going a lot further than I need to. Any advice from experienced folks is GREATLY appreciated. THANKS!!!
