Anybody out there used beak bits?  I have just fitted one to one of my hens who is feather picking, having tried everything else, anti peck spray, purple spray etc.  She is not a vicious creature, is not drawing blood, but is making my once beautiful blue hen look rather bare.  I fitted the bit today, and am a bit shocked at her reaction.  She doesnt seem to be eating, and keeps trying to get it off.  Also, as it holds her mouth open a bit, wont her mouth get too dry?  Will her breathing be affected? I saw a tiny speck of blood in her mouth after I fitted it - should I be worried?
