what is that yellow flower? looks kind of like a carolina jasmine vine but the flower sure is big. thats supposedly poisonous to cattle although mine eat it sometimes with no ill effects. or is it a st. john's wart plant? i cant tell.
Mark, it sure looks like there is an awful lot of stuff they can reach through the fence and eat. I saw you post before on what they found (U of F)but based on what I see in your pictures I would take a long hard look at what they reach through that fence.
