Hello my name is Michael and I am new to backyardchickens.com and have been having difficulty with my research into how many chickens I need if I want to try to make a self sustaining flock of chickens. I am interested in this for I would like to get into conserving some of the heritage breeds such as the Buckeye Chicken, Delaware, Barred Plymouth Rock, and Sussex. Have not settled on the breed I plan on going with and I have a few years before I can start since I am finishing up my last year and a half of school but want to research this thoroughly before I begin. I love the personality of some of these birds and want to work on making the meet qualities from some of these dual purpose heritage breed strains even better. Thanks for the help in advance and I look forward to getting to know some of you.
