I just spoke with Jamie of HART. She is very grateful for everyone's interest and support regarding this case.
I told her about CMHR and LB -- she tried to join the forum last summer, but said it wouldn't let her.
kaykay, I'll send you a pm with her phone number.
She is an extremely kind, caring woman. She said that the 15 horses are currently rotating between her arena and a quarantine pasture, but she has to be very careful to limit the rich grass. She has had a farrier out already, but they will all need a great deal of follow-up trimming. Many also need dental work, and I'm hoping to get her in touch with Dr. Richard Vetter.
Of course, they will all need foster homes and adoptive homes...I just wish we had more room here.
Thanks everyone for you concern!
