I have a SLW hen that I saw picking up straw and tossing it over her back yesterday while walking. She had just gotten out of the nesting box in the coop and we had just finished cleaning the coop while she was inside (she wasn't very happy as she made lots of noise). We have wood shavings inside the coop on the floor and the nesting boxes and straw outside of the coop. She did this multiple times as she walked to join the other hens, I'm just wondering what it means or why she was doing this? I have seen hens tuck straw under themselves when building a nest, but she was walking and not making a nest! Any idea's?
