This is my first time owning chickens (although they are just chicks right now). They are all almost 3 weeks old and I noticed that my baby Polish's wing is bleeding a little bit. I checked it out and it doesn't seem very serious. It looks like it's just bleeding where the feather like, connects if that makes sense. How do I keep the other chicks from pecking it and making it worse? And do I need to worry about infection? Any advice from you more experienced chicken owners would be so helpful!
