Hi there. My horse has recently (that I know of) been eating his own poop and I am wondering why. Although the muddy state of the paddocks has meant that he has been in much of the times, this week the barn owner was able to put the horses out. I have been able to see him during the pandemic and to ride him or at least let him run in the indoor. Also, he usually has hay in his hay net. Any thoughts on what might be going on? This seems to be a new behavior.
