My preference would be live trap and bullet to the head. Where the horses are now the owner will not permit that. I think she would permit us to trap and "release". Of course I would not tell her the release would be to the bottom of a pond, were it my choice. When we have our place it will be life trap and bullet to the head when the Mrs has her back turned. Will she care? Probably. Will she say anything... probably not because she will be glad it is gone. They carry disease that is bad for the horses. Otherwise would live and let live. Also a good excuse for me to get a .22 rifle with a scope to go after other nuisance animals. Reading up on poisoning them.... it seems to be very cruel as they take days to die. While I do not like them and want them gone, I am not going to torture them.
