From am to pm feeding he drank about 4 gallons of water and ate all his hay (alfalfa/grass mix). PM feeding time there were only 2 piles compared to the normal 4 or 5. He does not act or seem to be in any discomfort. He wants his food. So he ate his grain, drank another 2 to 3 gallons of water. Walked him for about 20 minutes and he pooped a little. Back in his stall he was given 1 flake of alfalfa hay (no mix).
Went back 2 hours later. Nothing. Gave him a little grain with some oil. About 20 minutes later he made a good size pile.
Fast forward to 2:30 am, 1 pile. Morning feeding today, only one more pile since 2:30. From 2:30 to 9am he drank about 2 gallons of water.
He acts normal. He was pawing at the stall door like he always does feeding time.
He is fed from a wall rack. That is not to say that he does not clean up the ground in his stall. He is still peeing normally.
Nothing in his diet has changed. Using the same pellet bedding as always.
In his stall he does drink less than when out. It is pretty icy so I don't want the horses out right now.
Any thoughts?????? 10 year old gelding.
