I inherited a couple of old hens from my neighbor. Both have their beaks cut back and poorly done at that !! One's is too short and is like a short duck bill in that it is rounded which makes it hard for her to peck. The other is even worse because the bottom is not cut and sticks out way beyond the top so she too has trouble eating. I can't do anything about the short round one but can I cut (carefully) the long lower one back ?
