I've never ordered directly from a hatchery, just bought hatchery chicks at the feed store. I don't know for sure if they were vaccinated or not, but I would like to have chicks vaccinated against Mareks from what I've read. I only have one friend with chickens and we work together but don't visit eachothers flocks. Otherwise I make sure I change clothes and shoes if I do get around any birds that aren't mine, which is very rare.
I'd like to get the Top Hat special from Cackle, but my layer coop plans are quickly filling up so I don't have extra spots left right now. And Blue Jersey Giants, Splash australorps, Blue Rocks, Delaware, Welsumer, Speckled Sussex, just a few of all the breeds I want at some point
