I have a small flock of 4 pullets and have planned for the addition of 2 more (toying with 1 more on top of that) in a month. The flock is 14 weeks right now, as is the 2 that are coming in a month. I purchased them as day or so old chicks from a farm store near us. I have no idea if they had any vaccinations when we got them. Because they were so little and they made no mention of quarantining them, I'm guessing not. The 2 coming in a month have been recently vaccinated, but with what I don't know. I haven't done any vaccinating. When I got the chicks I decided to not feed them medicated feed, partially because I don't want to eat the medications I'm feeding them, and also because I wanted to be a source for my mom to get eggs. A couple years ago she went through chemo and has had to change her diet. Store bought eggs make her sick, and organic eggs are ridiculously priced in her area. Would vaccinating my pullets defeat the purpose of keeping my eggs free from all the crap that commercial places pump into their birds and affect the eggs? I don't want my mom getting sick. My girls aren't allowed to free range because I have close neighbors, but there are at least 4 different turkey farms (all indoor birds) within about 4 miles. The closest is about a mile away. There is also some people that live about 2 city blocks from us that have penned chickens also. Would that increases my girls' risk factor. I did a search for vaccinations on BYC, the internet, and my states university extension service but didn't find what I was looking for. Does anyone have a list of vaccination guidelines for chickens? You know, like the ones that are out there for our kids. Do this vaccine for this at such and such age to combat whatever and the pros and cons of administering them. One of the concerns I have is with the new birds that I'm planning to introduce. Am I going to have to be worrying about those infecting mine or vise verse? If I decide to vaccinate, where do I get the vaccinations? Thanks.
