Hi I am a newbie. First, let me say I am delighted and surprised at how people get so passionate about their chickens (including us) and how much this site has helped. We have a baby bantam (10 wks), a mutt chicken (don't know what it is) a Plymouth Barred Rock and 3 NH Reds. I was wondering how hardy these guys are in the winter if I let them in a portable pen in the day and then the hen house at dark? The 3 Reds are like the mini army, the General, Sargeant and Lietenant towards the other three during day but ok at night. They don't seem to like each other...but are friendly with us. So we have been putting the General and her cohorts separate in the day. Hoping this will pass towards other chickens...Any thoughts or comments welcome, thanks in advance.
