Hello - Does anyone have any experience using poultry bits? I have 1 "mean old hen" who has been torturing my 2 new pullets for over a month now & nothing I've tried to stop her has worked (except physically seperating them of course!) so I've resorted to a chicken bit. I found some good plastic ones online from the UK & put one on her today. Obviously she doesn't like it but has stopped bothering the others. What I'm wondering is if I need to change anything with the food/water or way it's given to be sure she can still eat & drink. Any advice? Any experience using these? If so, how long did you have to use it? Indefinately? Thx!
