We like to put the horses in the back yard once in a while to eat the grass, especially since the pasture is burned up. My yearling has discovered the apricot tree, he eats them off the ground and when he can't pick one up, he'll eat them off the tree. I am concerned that this is not good for him and especially concerned that it will lead to colic. Am I right to be concerned about this? Or am I just an overly cautious mommy?
