Samantha is one year old, she is either a Cochin or a Brahma and was previously a docile featherbrained bird. She has started being broody and worst of all she actually pecks at our legs and then drinks the blood. I have added all sorts of extras to the food in case it is a vitamin deficiency but really believe it is is behavioral. Does anyone have any retraining tips to stop her from doing this before I have to cull her? My other two girls are very sweet. She is second in the pecking order.
