In the screenshot attached, you can see a doctor going to feed a sick hen. Although there is a bail of hay a few tiles away, they are walking a long ways to get a simple meal instead. Drafting and undrafting them does not change their behavior. If I forbid every food source on the map, except the hay, the doctor will simply choose not to feed the hen at all. It appears that doctors simply cannot feed hay to sick animals.
Doctors, when feeding animals, should be able to feed them hay.
To reproduce: Get a doctor pawn, and a sick animal in an animal sleeping spot. Place hay next to the animal, and remove all meals from the map, except for a few on the other side of the map. The doctor will walk all the way to the other side of the map to get the meal, to feed the animal, instead of using the hay.
