I have just discovered we have a TON of buttercup bur growing on our new property and I have missed my opportunity this spring to take care of it (it's already going to seed). I am getting some weeder geese in just a few days and now I"m worried about how the buttercup may affect them! It is poisonous to livestock....SO my questions are I know geese can be persnickety about what they eat - does anyone know if they WILL eat it? If they do, is it poisonous to them like it is to livestock? Any and all advice or info about this noxious weed and it's affects on animals would be appreciated! Thanks!
