My Silkie hen and rooster have been fighting a lot lately and I don't know why. They always stay together ever since they were chicks but now my hen is picking fights with the rooster. I know my hen is a hen because, well eggs. I am getting very worried because my hen has left several gashes on my roos neck. Luckily they are not deep for now. But after I stop the fighting they calm down and hang out together with no fits and they're good friends again until the next day. Is there anything I can do or is it normal for silkies to have extreme bipolar relationships.
