Hello everyone I am new to this so forgive me if I come across crazy. I am the first one to have chickens since my great-grandparents and they are gone. My mother and father in law have chickens and now so do I. They have had chickens for over 30 years and this year thier chickens have started plucking eachother bauld! I have done some research and found that they are lacking protein. Is there anything special that we can start giving them. My chickens are free ranges, theirs are not. I have only had my chickens a couple of weeks so mine don't look that way. Are there any foods that we can give them that are high in protein that will help this problem? your help is much appreciated! Thanks!
