Hello, I am so excited to start my new flock. I had one a year ago and they all got sick. . I'm nervous that will happen again. Anyone have thoughts on vaccinations and how that will effect eggs? We love the eggs. I am also trying to decide how many to get. We have a dog side run on our house that we have turned into a chicken coop and run. We let them out a couple of times a week in the backyard. Any suggestions or thoughts would be appreciated. Also, I love cute chicks but I don't want to wait the twenty weeks til they start laying. Does anyone know who might be selling laying hens fully grown? Thanks for any input!
