I am beside myself - from the cam she looks quiet and like she was looking for food. But no poop in stall and she immediately started pawing when I went out to feed. VERY alert, screaming as she would for food, so I fed her first (making everyone else angry). When she wouldn't eat, I let her out, she trotted around, over to Toffee's stall where there is more hay outside, but just nosed in all the hay. Put her on lead, took her out to lawn and all she would do was paw. She does not look sick or like a colicky horse - at least none in my experience - more like frustrated. Hard to tell about water because Bunny dumps one bucket but she had drunk some last evening.
I hope the Ca I gave helps... I did not take temp - thought about it and will go back out and do it. I have to get some food myself, as I am about ready to pass out. I can, of course, also call my vet.
