I have 8 hens that are 8 weeks old and they have began to fight and confront each other. They are allowed to free range every other day and they tend to want to battle each other.....is this normal behavior for these 8 week old hens who have all been raised together and are the same age? Maybe they are frustrated being cooped up in a small coop. I thought perhaps it is because they are in a fairly small coop for their size. I am wanting to put them into the larger coop with two older RR Red hens but afraid they are not big enough yet to defend themselves from the older chickens. What a dilemma.....what should I do? Let them fight it out? See some blood in their small coop like one has been hurt but don't know which one. I noticed this after they had been all penned up all day long. Any suggestions?
