My new silkies are snobs! They stay in the coop with the others, but they don't really socialize with them. When I open the door for everyone to go out and free range, they just stay in. Everyone else can't wait to get outside and play, but not them! Is it because they are older than the others? Or perhaps they have never been allowed to free range before and don't know that they can? They are very calm birds, and let me pick them up and pet them with little or no fuss.
