As I was saying this is VERY much Opinion. In fact, most backyard chicken owners only do the Mareks vaccine and that and the coccidosis vaccine are the Only ones I feel are important. Possibly the fowl pox vaccine as well. The coccidosis vaccine IS only given at hatch. I don't use it. Instead I feed MEDICATED chick feed. The food helps prevent coccidosis.I've personally not given the fowl pox to my birds.What I was trying to explain in a earlier post was other than Mareks vaccine, the others can do more harm than good in my opinion. I've had it personally harm my flock.When I first started out I was very much like you wanting to give many vaccines for the protection of my flock. what I didn't know then, and learned through sturdy after the loss of my vaccinated birds is that the other vaccines, most are LIVE VIRUS. meaning it gives the bird a small amount of the disease in order to raise immunity. What I didn't know was if they can't fight the virus, that alone can KILLS them, like it did mine. I also learned the live virus vaccines OTHER THAN MAREKS (the MAREKS vaccine is NOT Mareks) (it's derived from a similar turkey virus so it DOES NOT give them Mareks or make them carriers. But the others DO MAKE THE BIRDS CARRIERS of the other bad viruses your vaccinating to prevent! What this means is they will give new birds brought to your property or they are around the virus!! So the other vaccines are in my opinion not important. not only that they make carriers of the very disease your trying to prevent out of them! I am speaking from experience.I lost every bird that was vaccinated with the live virus of the disease itself. If your curious the vaccines avaible, look online at First State Vet Supply. He carries them. However, I can't in good conscience recommend anything but the Mareks vaccine which I feel is extremely important. so if they were mine, I'd only give Mareks. You can see the rest online at the vet store I recommend. If you do your research on the others I am fairly sure you will agree with me. it devastated me loosing my birds from giving the vaccines!I should have done more research first. That said, the only imordant vaccine is Mareks. The others can cause a lot more harm then good. I really hope I've helped you out a bit. let me know.
