Please help,,,My penciled wyandotte center left in picture I attended a backyard chicken talk at my local small farms expo, The talk was given by a gentleman who has had poultry for nearly sixty years. My concern is a comment he made about chickens with pointy or razor breast bones,(cull/destroy because this is a sign of mareks). I discovered this when removing eggs from a broody chook, she seams to be of good health normal droppings, eats well, has raised 2 lots of chickens. Bought Jan 2014 at 8 weeks old, I want to do the right thing and not spread germs. but am having trouble finding information on this symptom.
