Well today I saw Morgan drinking from the pond in her pasture. I didn't know she was drinking the water and it isn't very fresh. Because of all the snow and rain we are having the pond has risen but it is quite muddy and dirty. I can't believe she would drink it. Is there some type of fish that I can put in the pond to help keep it clean? Is it okay for the horses to drink it? They have a trough and I just filled it yesterday. Should I be concerned that she is drinking the pond water. I watched her go to the edge and drink it and she didn't seem to sink, but like I said it is extremely muddy here. During the summer the pond was dried up. But with rain and everything it has produced itself again. Any suggestions? I thought about just runing fence around it so they couldn't even get to it, that is if it is bad for them to drink it. If not then I'll just leave it. Someone had told me once there was something you should vaccinate for if you had a pond and now I can't think of it, any ideas. Oh well, any info would be great and stuff. Thanks.
