i have 1 feather pecker, she's always done it, i think it's just a habit she developed whilst a barn hen, i've watched her systamatically peck poor Lois and Lois just sat there like a lemon and let her, mine free range the farm all day and have access to oyster shell and layers pellets 24/7 so i don't think with her it's a dietary thing, if you can find out the reason for your feather pecker you'll have a better chance of stopping it, stockholme tar never worked for me but if you are thinking of trying it wear a bin liner and rubber gloves ![happy :)](https://chat.allotment-garden.org/Smileys/green/smile.gif)
I read somewhere that the propensity to "peck" at things is genetically inherited. Hence Blue tits love to peck
I suppose that various breeders when choosing preferred qualities may go for things like egg quantity and size and ignore troubles from pecking as they think bits bumpers specs and debeaking will stop the problem. Which may be why many modern hybrids can suffer from this trait.
It's something to remember when breeding from your own birds. If they have qualities you admire, and qualities you dislike they will probably be passed on in equal quantities.
All the best
