I too am looking for solutions to my chicken feather picken problems. I now have over 300 birds and this problem is happening in several of the coops. I wish it would stop because it is making me crazy. My formerly beautiful roosters, are just that and I have had blood drawn so need to do something soon. I also have feet pickers which is another nasty problem. I am going to order some Bumpa Bits, if I can get them to Canada. I can only find a UK website and have had no luck trying to order from there. I won't be wasting my money on any sprays or body creams as it seems, they don't work. If I can't get the BBs then I will relunctantly have to start culling the problem birds. Thanks for sharing.
