I'd like to set up a scenario and then ask for you feedback.

These are 3 of the 11 horses that belong to someone you know.  This person, while not a close friend, is more than merely an acquaintance.  They started with two horses and in the past 3 years have increased their herd to the 11 they now have.

They also have accumulated 40 chickens, 1 miniature stallion, 5 dogs, 6 cats, 10 birds and a chinchilla.  These animals appear to be in good condition.

Of the 11 horses 4 have been added in the past 3 months.  The horse's area consists of twisted wire attached to trees around an all wooded area - no grass.  There is a 3 sided run in - large enough to accommodate perhaps 3 horses if they squeezed in.  The part of the country they live in gets moderate rain and snow.  In the winter the temperatures sometimes drop below 0.

In the past year they have had 3 foals born - 1 died, the remaining 2 are now yearlings.  5 months ago, they had to have a mare "put down" due to colic.  2 of the horses are "green" broke.  A couple have had some ground work.  Nothing has been done with the rest of them.

You have tried to talk with them on several occasions about horse care and nutrition.  Each time they became very defensive.  You have asked your vet to speak with them, he has and with the very same results, they became very defensive.

The last 2 times you visited, the round bale feeder in the horse's enclosure was completely empty.  You did not see any water available.

Put yourself in this situation and share what you would do.
