CHAPTER XII. Incubation
Care of Eggs for Hatching. Since egg production usually begins early in the spring while the weather is still cold, it is necessary to gather the eggs at frequent intervals to prevent their freezing or becoming chilled. Later in the season daily collection will be satisfactory. The eggs as collected should be kept in a cool place and where the evaporation of the egg contents will not be too great. If set at fairly frequent intervals, there will be no difficulty on this score. If they are to be kept for some time, they may be stored in bran to prevent evaporation. It is well to mark the eggs as gathered with the date they are laid so as to overcome the possibility of saving too long any eggs for hatching.
Some goose raisers think that it is best to wash goose eggs before setting them. This belief is based on the fact that when a goose makes her own nest and has access to water in which to swim she comes on the nest with her feathers wet. It is to simulate this condition that the eggs are washed. Certainly any dirty eggs should be washed.
Methods of Incubation. The most usual methods of hatching goose eggs are by means of the chicken hen and the goose. Incubators may also be used but do not as a rule seem to give as good results as they do with hen or duck eggs. Turkey hens may also be utilized for this purpose but are not commonly available although they make good mothers. Probably the most common method of hatching is the use of chicken hens. Next common is to allow the goose to hatch her own eggs. Goose eggs hatch well under hens or geese. During the height of the season nearly every fertile egg should hatch if the breeding geese are managed and fed so that they are in good condition. Early in the season the eggs may not run as fertile or hatch as well as later.
Period of Incubation. The period of incubation of goose eggs is approximately 30 days, but may vary from 28 to 33 or occasionally even 35 days.
Hatching with Chicken Hens. Chicken hens are used very commonly to hatch goose eggs both because they give good results and are readily available and also because it is desirable to take the first eggs laid by the geese away and not to let them get broody and sit so that they will lay more eggs. For the latter reason practically all the eggs laid early in the season are hatched by chicken hens.
The nest can be prepared for the hen either in a suitable place in a poultry house or in a shed or other building or in a box or barrel on the ground. As soon as the hen shows that she is ready to sit by staying on the nest, in which has been placed a nest egg or two, for a couple of nights in succession, she may be given a sitting of eggs. Four to 6 goose eggs will constitute a sitting for a common hen. The hen should be confined to the nest being let off only once a day for exercise, feed and water.
The sitting hen must be given good care, being even more particular in this respect than when she is sitting on hens' eggs as the period of incubation is longer. In addition to being careful to see that the hen comes off her nest for food and water she should be dusted 2 or 3 times during the hatch with some good insect powder to keep her free from lice and therefore contented to stay on the nest. Two or 3 days before the goslings hatch she should be dusted with especial care so that the goslings will be free from vermin.
On account of the large size of the eggs the hen should not be depended upon to turn them and this should be done by hand once or twice daily.
Hatching with Geese. All breeds of geese will hatch their eggs although some are more persistently broody than others while there is a considerable difference in individuals in this respect. Toulouse and Chinese are perhaps the least broody of the breeds and are sometimes termed non-broody. The eggs laid by geese are generally gathered as laid. If this were not done they will become broody and stop laying quicker than they do under this treatment.
The goose should be allowed to make her own nest. Often she will do this in a barrel, box or other shelter if these are conveniently available. When she shows that she is broody and has stopped laying she should be given a sitting of eggs which will consist of 10 or 11. Geese are often difficult to manage when they have young.
Wild and Egyptian geese should always be allowed to make their own nests which they like to do on dry ground near the water, using straw leaves or similar material to make the nest. They should not be disturbed as they are ugly during this time. They will hatch practically every egg.
Breaking Up Broody Geese. A goose which shows a desire to sit, can be broken up quite easily by confining her to a slat-bottomed coop without any feed, but with plenty of water to drink, for from 2 to 4 days. After being broken up she will generally commence laying again after an interval of a few days.
Hatching with an Incubator. While it is more difficult to hatch goose eggs in incubators than it is hen or duck eggs, this can be done by an experienced operator with a fair degree of success. The incubator should be operated at a temperature of 101.5 to 102.5 degrees F., with the thermometer so placed that the bulb is on a level with the top of the eggs. Beginning with the third day, the eggs should be turned twice a day as with hens' eggs. Beginning about the tenth day, the eggs should be cooled once a day, and they need more cooling than hens' eggs require. They should be cooled down to a temperature of about 80 to 85 degrees. All goose eggs whether in incubators or under hens or geese should be tested once during the hatch. The best time to do this is sometime between the tenth and fourteenth days, when any infertile eggs or dead germs should be thrown out.
Moisture for Hatching Eggs. Where eggs are being hatched in an incubator, there is need for the use of considerable moisture. It should be added first at about the end of the first week of incubation and should be repeated a couple of times during the second week. This can best be done by sprinkling the eggs liberally with water heated to about 100 degrees. Beginning with the 15th day and until 2 or 3 days before the eggs are ready to hatch soak them in warm water for from one-half a minute to a minute once every 2 or 3 days. For the last 2 or 3 days do this daily.
When the eggs are being hatched by chicken hens or geese in nests indoors or in boxes or barrels and in dry weather, moisture should be added in the same manner and with the same frequency and amount as in the incubator. When the nest is on damp ground, it is not necessary to use any moisture on the eggs.
Hatching. Goslings as a rule hatch rather slowly and somewhat unevenly, especially when under hens. For this reason it is well to remove each gosling as it hatches from under the hen or goose and place it in a covered, cloth-lined box or basket and keep near the stove until the hatch is completed. As soon as the hatch is over, the goslings that have been removed from the nest can be put back under the hen or goose which is to be allowed to assume the duties of motherhood. _
