Every time I lift the net from the top at least 6 sometimes eight the chicks fly to the top of the box. They will walk all around it and they are looking around like where can I go now. One of them (Reddy) did fly from the top of the box to a book shelf close by and another (Blacky) tried to fly to the top of the fence/gate I put behind and to the side of the box. I was also holding on yesterday and had my arm extended out and another flew from the box to my arm. That was pretty cool =o) They are a lot of fun to watch!! When this cold spell leaves we will put the 5 week olds (actually 6 weeks by that time) in the chicken coop outside and I think we will leave the younger ones in for another week or two. I’m really glad we did this!
