Hi all, have just finished building my first coop for the backyard, and am now in the market for some chickens here in New Zealand. Have come across one lady with 21 week old hens which are just starting to lay eggs. If we are wanting organic/free range eggs, would I be best to find some hen's that aren't vaccinated? Do chickens mandatorily have to be vaccinated. There isn't much risk of anything in our backyard, no predators or anything. Any help you can give would be much appreciated. Should I ask this lady perhaps to raise some chicks vaccine-free or will the majority of chickens that I come across be vaccinated?
