Hello to all. I have been reading posts on the board for the last 6 months. Just joined this great site today. I also just got my first rooster and hen. I am now wanting to add more to my collection. Everyone said this was addicting and now I see what they mean. My question is, Can I add more hens without problems? They will generally be the same size. My pen is 10x10x6 if this helps or matters. Thanks in advance. Can anyone tell me what he might be?
