I am new to raising chickens. I have 6, 2 each rhode island reds, barred rocks and white leghorn. My one barred rock is the biggest of the bunch and today I noticed her beak bleeding. It looks like she may have stuck it in something and I'm not sure what to do. I don't think the others have been pecking at her and it doesn't seem to affect her eating. I've read about blood on a chicken making the others peck it to death...............do I need to worry?? They are all 6 weeks old. I could use some advice. Thanks.
