A special building is not required for brooding small numbers of geese. Any small building or a corner of a garage or barn can be used as a brooding area for a small flock if it is dry, reasonably well-lighted and ventilated, and free from drafts. Cover the floor with 4 inches of absorbent litter material, such as wood shavings, chopped straw, or peat moss. Maintaining good litter requires frequent stirring, removal of wet spots, and periodic addition of clean, dry litter. Be sure litter is free from mold.
Heat lamps are a convenient source of radiant heat for brooding small flocks.
Use one 250-watt lamp for each 25 goslings. Because goslings are larger in size, with some brooders it may be necessary to raise the hover 3-4 inches higher than for baby chicks. Have the temperature at the edge of the hover 85 to 90 degrees F when the goslings arrive. Reduce the temperature to 5 to 10 degrees per week until 70 degrees F is reached. Confine the birds to the heated area for the first 3 or 4 days with a corrugated paper or wire mesh fence.
