I have never had chickens, but I am preparing for my first small flock in the Spring. My mom keeps bringing up how she doesn't like how they peck the feathers off of each others' backs. My questions is this: Does the pecking order happen in every flock? Is there a way to avoid them loosing feathers? Does having more room to roam help? Are there some breeds that are kinder to each other? Or is this one of the facts of life associated with owning chickens? I do not plan on owning a Rooster if that makes any difference. Thank you for your knowledge and advice to a novice chicken owner!
