The only other furnishings needed are a feed trough and a drinking vessel, but it is advisable to have a tub or a pan in which the birds can take a bath, and to supply them with water in this once or twice a week. The drinking vessel must be one that they cannot get into, for if they can get into it they will certainly do so. An ordinary wooden water pail, or a small butter tub with the part above the upper hoop sawed off, makes a very satisfactory drinking vessel for adult ducks. It will hold enough water for the ducks to partially wash themselves, which they do by dipping their heads in the water and then rubbing them on their bodies and wings. For the regular bath for two or three ducks one of the largest-sized bath pans made for pigeons will do very well, or an old washtub cut down to six or eight inches deep may be used. For a flock of eight or ten ducks a good tub may be made from one end of a molasses hogshead. The bath should always be given outdoors, because it takes the ducks only a few minutes to splash so much water out of the tub that everything around it is thoroughly wet. The drinking water should also be given outdoors whenever the houses are open. As the ducks of the breeds usually kept can hardly fly at all, very low partitions and fences will keep them in their quarters, but to keep other poultry or animals out of their yards it may be necessary to build higher fences. For the heavier breeds, like the Pekin and Rouen, fences are usually made from 18 inches to 24 inches high. The ducks will rarely attempt to go over these, but occasionally a drake learns to climb a two-foot fence by using his bill, wings, and toes, and may then manage to get over a higher fence. For the small, light breeds, fences 3 or 4 feet high may be needed. If their yard is on a slope and is large enough to give them a chance to start a flight high up on the slope, so that they will rise above the fence at the lower side, it may be necessary either to put a very high fence on that side or to cover the yard. While the fence for ducks need not be either high or strong, there must be no holes in it that a duck, having put its head through, could by pressure enlarge enough to let its body pass. A piece of wire netting that has begun to rust a little may be as good as ever for fowls for a long time, but if used for a duck fence it will be most unsatisfactory, because the ducks will soon make many holes in it. If wire netting alone is used, it should be fastened to the ground with pegs every three or four feet.
