Just starting my own "flock" and learning ALL new things. Very much a beginner. I have recently raised 14 Rhode Island Reds to 17 weeks (so far) which are perfect for our situation including self sufficiency, which is our main goal. Question; is it better to have a variety of breed in your flock or can I just stick with Rhode Island Reds for the entire flock to have a fair amount of success given our goals? Thank you for your reply.
