Hi, I let my chickens free range in the backyard during the day if I'm home. If it is windy or rainy (not that cold), or sometimes just because, they sit together on the back doormat (glass door that they can see us through). Sometimes for extended periods. Everything i've read says this isnt quite normal. That they should be active for most of the day. They all are eating and laying normally and will toddle off to the nesting box to do it, then return. They also free range quite actively when they aren't sitting. So, is it normal that they are "resting" or "keeping warm" this way?
