[Jacob-list] Re: dead sheep

Thanks to all who replied to my post about the death of my sheep.  I am still 
trying to figure out what killed him.  I walked the field today and didn't 
notice many any weeds growing yet, but I did see that a big limb from a dead 
black walnut tree had fallen among some other dead limbs that were already 
there.  I noticed that on the part of the tree that is still standing, there 
are little ferns growing. There were no ferns on the part that had fallen.  I 
recalled seeing Theo over there nibbling at the fallen tree a few days before 
he died.  Could ferns growing on black walnut be toxic?  

Also, some of the ground cover plant, vinca (with little purple flowers) has 
crept into the field.  I kept a close watch on it last year and the sheep 
nibbled on it some and they never had any problems.  Does anyone know if that 
plant is toxic?  I asked our extension agent and he didn't know.

Thanks again to all who answered my post.
