Abstract: A prefabricated individual calf shelter has front and back end walls, first and second side walls, a top wall and an open bottom. All the walls are formed of molded fiber glass or other plastic as elements of a single molded housing. An animal door is located at one side of the front wall and the other side of the front wall cooperates with its adjacent side wall to provide a sheltered corner area for the head and front body of the animal. A feed opening in the side wall provides external access to the sheltered corner and is selectively closed by a cover. An externally and manually operable retaining element selectively holds the cover in closed position. The fiber glass housing has its smooth gelcoat surface at the inside of each wall and a rougher surface at the outside. The housing includes reinforcing and drainage features arranged for convenient molding, stacking, transporting and farm use of the shelter.
