I have 9 chickens, one rooster , the rest are hens. I have deer netting around the fence 7' high to keep them from flying over the 4' chain link fence. One hen got stuck under the netting, and the others all started pecking her, till she had bare spot. i got her out and she survived. But now I see one of the smaller hens is being pecked and sort of an outcast by the other hens. I let the flock come out of the pen into our back yard often so I don't think they are stressed or anything.I don't think their coop area is too small. I have just noticed this lately, my flock is just over a year old. Another question, my chicken coop is 4x4, with 7 egg laying boxes, this coop is attached to a 10'x10' dog fence where the flock roost at night up on a ladder roost. All this is in a 20'x15' fenced area. This gate is left open to the coop so the flock roams the large fenced area all day, then some times we open the gate so they can come in our back yard. So we have 9 chickens now, and my wife wants 6 more chickens. Do you think we have the room ? We had 12 at one time but have lost a few since.
