It was about 3 or 4 months ago I reached towards one of my hens when she was in the nesting box and she made a sound that was like Gaaaaaa! So i just thought that she was protecting her eggs so i left her alone. The next day,she was out of the nesting box,I reached towards her and she made the same sound. She still makes that sound when I touch her or reach for her. If anyone knows why she is doing that could you tell me. Thanks.
