I have 10 backyard chicks 2 weeks old still in the brooder, here in Georgia. Half were vaccinated for Marek's at the hatchery, and 5 are from a farm nearby who does not vaccinate. A friend of mine who is a more experienced chicken owner asked me if I was going to vaccinate for fowl pox. I had to read about it...and watched a video on Youtube to see how relatively easy it is to do. Is this necessary? There are other vaccines from Murray McMurray that are available, for respiratory diseases. I am not going to show my chickens, and do not plan to add more, so do any of you vaccinate more than Mareks?
