Artificial Incubation and Brooding
Incubators are used as successfully in hatching guinea eggs as in hatching hen eggs. They are operated in exactly the same way for either kind, except that the thermometer is lowered sufficiently to make its relative position above the guinea eggs similar to its former position above the hen eggs.
Little has been done in the way of brooding guinea chicks artificially. They are naturally of a wild nature and require free range to grow into strong, vigorous birds. Nevertheless in one case a New England poultryman hatched 200 guinea chicks and succeeded in raising about 125 by brooding them in exactly the same way as common chicks in a hot-water brooder house. On bright warm days the chicks were allowed to run in a yard about 50 by 100 feet, which had been planted to corn, and thus afforded some green food for them to pick at. This yard was inclosed by a 5-foot wire fence of 1-inch mesh, with 2 feet of 1⁄2-inch mesh around the bottom. The guineas began flying over the fence when they were about 6 weeks old, and from then on they had free range and were allowed to roost in the trees. Other poultrymen who have tried brooding guinea chicks artificially report utter failures, sometimes due to white diarrhea, and at other times the birds seem to become weak and die from no apparent cause except too close confinement.
