I have an 8month old colt who for the past few days hasnt touched his grain. Which is weird cause he never leaves a drop in his bucket. He's had grain since he was 4 days old and now just doesnt seem interested in it. He does drink his water, and was eating his hay really good until the other day when I noticed him just nibbling at it. Eating like one straw at a time. He's been in a stall for the past couple of months working on weaning and ground work. I just started turning him out in his own corral during the day and back up at night. That the only change I've made in any of his routine. Im worried it may be colic... but he's drinking water, and is pooping regularly. There is nothing lodged in his mouth that seems to be creating stress in his mouth. Im at a total loss. Even the vet doesnt know what to think of it from what I've told him over the phone. He can't come out until tomorrow afternoon to check on him, but I just pray there is nothing serious with this. He hasnt eaten any grain in almost 3 days.
