The pea-hen produces at three years old. In the first year she will lay one or two eggs, in the next four or five, and in the remaining years twelve, but never beyond that number. She lays for two or three days at intervals, and will produce three broods in the year, if care is taken to put the eggs under a common hen. The males are apt to break the eggs in getting at the females while sitting, and hence it is that the pea-hen lays by night, and in secret places, or else sits on her eggs in an elevated spot; the eggs will break, too, unless they are received upon some surface that is soft. One male is sufficient for every five females; when there are only one or two females to a male, all chance of their being prolific is spoilt through their extreme salaciousness. The young breaks the shell in twenty-seven days, or, at the very latest, on the thirtieth.
Geese pair in the water, and lay in spring; or, if they have paired in the winter, they lay about forty eggs, after the summer solstice. The hatching takes place twice in the year, if a hen hatches the first brood; otherwise, their greatest number of eggs will be sixteen, their lowest seven. If their eggs are taken away from them, they will keep on laying until they burst; they will not hatch the eggs of any other birds. The best number of eggs for placing under the goose for hatching, is nine, or else eleven. The females only sit, and that for thirty days; but if they are kept very warm, then only twenty-five. The contact of the nettle is fatal to their young, and their own greediness is no less so—sometimes, through over-eating, and sometimes through over-exertion; for seizing the root of a plant with the bill, they will make repeated efforts to tear it out of the ground, and so, at last, dislocate the neck. A remedy against the noxious effects of the nettle, is to place the root of that plant under the straw of their nest.
