I have five Bantam hens. A few months ago I took in a sixth hen, well the past month i've been keeping her in a smaller cage within the coop (trying to get them used to each other) well I also have noticed that my first five hens are missing a few feathers on their necks. I saw them fighting with each other one day and pecking and holding on to the neck! To make matters worse, the won't accept this new hen into their flock. My hens have been missing feathers for a few months before I got the new hen so I don't think it's because of that. But why would they suddenly start fighting each other? And I don't know what to do with the new hen since they won't accept it. Is it normal for them to attack the new one just to put it in it's place? I also heard of putting it in there at night, but that didnt work, I might try it again though. What should I do? They have plenty of food and water so I dot know why they would hurt each other like that?
