His diet hasn't changed, nor his appetite. His teeth were floated in October. He was wormed about 4 weeks ago. He gets blanketed for turnout.
The only thing I can put my finger on is the four hour round trip to the show two weeks ago. His gums look good, his temp his fine, gut sounds are good.
So what I do? I'm at a loss. He's on Nutrena Safe Choice, gets hay in the morning and night and free choice during the day.
