The birds must be got out early so that they will begin laying in the fall and be ready to incubate by the time you want them. It is well to have a room for the purpose and have the sitters by themselves. The nests should be in rows around the room, the feeding and water-troughs in the centre, with the dust-bath at one end. The nest boxes should be some fourteen inches square and about a foot high. Each one should be furnished with a slide so that the bird can be confined when necessary. If the slide is planed, all the better, as the date of the sitter can then be marked on it. The first thing is to prepare the nests. There is quite a knack in this; indeed, success largely depends upon this one thing. The best material for this is soft hay or straw, cut six or eight inches long, placed upon a soil bottom. The sides of this nest should be packed hard, the bottom smooth and slightly concaved, not too much, as the tendency then would be to break the eggs if they crowded towards the centre. There should be plenty of room in the nest for the bird's feet and legs and the eggs too, so that she can turn at will without danger of breaking them. A piece of tarred paper five or six inches square, should be placed on the soil in the bottom of the nest; the whole covered with a half inch of finely cut straw. A few porcelain eggs should be placed in the nest, and when a hen shows a strong desire to incubate she should be placed upon the nest and the slide closed, giving the bird all the air she needs. This removal should be made after dark as the birds are always more gentle then. It is well to set a number of hens at once, if they can be had, for reasons that will shortly appear. If the birds take kindly to the porcelain eggs they can be removed the next evening and replaced with ducks' eggs. As they are much larger than hen's eggs, nine or ten will be enough in cold weather and eleven or twelve in warm; proportioned, of course, something to the size of the bird. I always take the birds from their nests at a certain time every day; they will learn to expect it. This should be done during the warmest part of the day. Handle Your Hens Carefully. Now is the time to exercise caution. Take your birds off carefully several at a time. If one should fly in your face, break her eggs and spatter the contents over your person, and you should feel like wringing her neck, don't do it; you would only be so much out. Take things easy, don't get mad; she may do better next time, if not, replace her with one that will. When taking your birds off in cold weather cover the eggs at once with a circular piece of heavy paper previously prepared, and they will not cool perceptibly during the fifteen minutes the birds are off. Be sure and return each bird to her own nest, for if you have an uneasy sitter, though she may spoil her own eggs, she should have no opportunity to spoil those of others.
