Until the coop is ready, I take my chicks (3 weeks old) outside for some fresh air and play. They are in an enclosure in the grass. I noticed that one of BO pullets started laying down on her side, stretching her wing out and exposing her body. I watched her, thinking that something might be wrong. Eventually one of her buddies flapped over her and she got up. I thought, "That's weird." Then I noticed my one cockrel do the same thing. These two did this off and on for the first 5 minutes of their outside time, then they got up and flapped, played, chased bugs, scratched etc. just like my other 4 chicks. What's up with that? Were they hot? Enjoying the sun? Catching a breeze? Testing poses for an upcoming edition of Chicks Gone Wild? We live in GA and the temp outside is about 80-85 today.
