I'm sure this question has been asked before and is somewhere in the archives, but I couldn't find it, so I apologize for the redundancy. My son and I are getting ready to start a new flock. We have raised chickens for about the past 10 years and have had some flocks that were extremely pecky with eachother and only one flock of black sex-links that didn't peck at all. My son thinks the pecking issues are due to mixing different breeds together and wants to limit this flock to only 1 or 2 breeds. I really like to mix my flock. (I always feel like a kid in a candy store when I am picking breeds...I want some of everything!) and I love the sight of all those pretty hens foraging around the backyard. I'd really love some feedback from some of you folks. What is your opinion on mixing breeds? If you do mix them, do you try to keep them all of a similar weight/size? Your imput would be very much appreciated. TIA.
