Three of my Silkie pullets began laying this week! Yay!!! This morning, after laying, of the pullets was walking around their little yard picking up twigs and throwing them back over her back! What is the reason for this behavior?? I have seen my big laying hens pick at the nest box material while sitting in the nest box waiting on an egg, but never the behavior that this little silkie hen is exhibiting! What is going on?
