TESTING PIGEON EGGS
If you want to know whether an egg is going to hatch after the hen has been sitting for some time look through it, if it is clear it will not hatch and might as well be thrown away. If it is partly clouded, the egg will hatch but not for several days. If it is dark all over except at the large end, the young bird will hatch in three or four days, or it has died. To find if it is alive, put some water in a pan having it as warm as the hand can be held in it without burning. Set the pan down and put the egg in the water, little end down and let it float. If the bird is alive it will struggle in the egg and cause it to bob around in the water. Testing eggs is not necessary unless it is noticed that a certain pair have set for a suspiciously long time.
