Hi gang, I need a new addiction and I'm thinking that hatching eggs might be the addiction I'm looking for. However, I'm really hung up on the Marek's issue and feel that I should be vaccinating any chicks that I hatch. How many of you vaccinate? Needles make me queasy. As in, really queasy. As in, even talking about needles gives me an anxiety attack. How difficult is vaccinating? I've looked it up online and can only make it so far into reading about it before I feel ill. I'm not sure I can do it. I feel ill again.
