I went in to clip one of my young silkies nails. I'm not quite sure the sex yet because it's only about 3 1/2 months old but I'm leaning toward male.anyway I clips his or her nails then started petting it's beard. It loved it so much it started purring. That little silkie purred for about 30 minutes straight while I gently petted it's beard face and head. It was the sweetest sound ever! ! I always love it when they purr. I know they are truly happy and comfortable. It always surprises me a little when they start to purr. Who would have thought that chickens purr too when they are happy? This was just a sweet little story I wanted to share with you all. Don't you just love it when your chicken purrs??
