I bought my horse Winchester almost three months ago. He is a 10 y/o gelding.
He becomes extremely aggressive towards my old mare around feeding time. (They are always fed separately in different pens) The rest of the time he wants to be near her, pitching a fit if I wash her...trying to bite her and running and calling to her like a maniac...but she is constantly trying to get away from him, and never relaxes. Since he has caused her so many injuries over the past few months I decided to fence half the property and keep them separate.
Well I have been watching that water trough since the seperation and he will not drink. I thought maybe because it was black and changed it, then put his favorite red bucket out there, ect. It was two days this morning without him drinking. Trough is still full (I marked it). I am in South Florida and its in the 80's & 90's, so I am VERY concerned. I let him back in with her and he drank, and drank, ate her crumbs of feed & hay, tried to eat her alive, then drank more.
