I was recently told by a friend since my roosters are getting a little too rough with my hens and there plucking off their back feathers. That I should give them bacon grease in their water because there missing some type of mineral and thats causing them to do this. Is this true or is my friend pulling my feathers lol. Im just nervous that one day I might come out to my hens and see a naked chicken running around and how can I promote feather growth and how long does it take to grow back? Thanks for the help much appreciated.
