I moved all of my chicks outside this last week....they will be 4 weeks old on Tues. I was a little nervous about what the reaction would be, but they have loved it. Every morning they are sitting at the coop door waiting to be let out, and then it's a mad dash to see what kind of goodies have been left since the night before. Up until last night I had to place them back in the coop at night...they would cuddle outside the door come dark...but last night I went out a little later and they had all placed themselves back in the coop! I am totally obsessed...my husband just laughs at me. And to help my addiction...I have 12 goslings coming on Wed that my husband ordered for me.
