Hey guys so I have 4 buff orpingtons that are 20 weeks old I got them 2 weeks ago when I got them I notice that one of them had a bald patch on her bum and once I spent some time with them noticed that there was one of them doing all the pecking I went and bought some anti pecking spray from the poultry suppliers I used if but it doesn't seem to be working because the hen is still pecking at the feathers does anyone have an idea why this might be or suggestions on how I should try and solve the problem thanks for the help
