DUCK DOLLARS 47 
This testing should be done in the incubator house alongside of the 
machine. In very cold weather we use a cloth and cover the eggs while 
we have them out of the machine, so that the heat can be kept in them 
as much as possible. Test a whole trayful before putting them back into 
the incubator. Work quickly in cold weather, 
There is no more testing of the eggs, but you must turn them in the 
incubator night and morning, twice a day, right along until hatching. 
If an egg shows black while you are doing this at any time, such an egg 
should be thrown out, for it is rotten. If when you open the incubator 
you detect a bad smell, you can find the egg which is at fault, if you 
cannot see it, by running your nose along the eggs, held close to them, 
until you come to the bad one. It should then be thrown out. 
The eggs should begin to pip on the twenty-fourth day after being 
put into the machine. When you see this pipping starting among the 
eggs, stop turning them and do not open the machine 
until the hatch is over. The hatch should be completed, When “They 
if the machine is run properly, on the twenty-eighth day. Batch 
Remove all eggs that have not hatched at that time, and all shells. 
The temperature of the machine for the first three weeks should be 
102 degrees, and for the last or fourth week 103 degrees. 
In minor matters not covered by our directions under ‘‘ The Egg,” 
run the machine according to the directions which go with the incubator. 
After hatching, the ducklings should be left in the incubator from 
twelve to thirty-six hours, until they have dried off. Just before the 
eggs hatch, the ducklings absorb the yolk and live on ; 
that for thirty-six or forty-eight hours. If they are Don’ tbe toe 
taken out of the machine too quickly they are not Ounce 
hungry and will not eat. You should leave them in the machine from 
twelve to thirty-six hours, so that they will not only be dried, but hungry. 
Take them out of the machine gently. Pick them up or guide them 
with the fingers by handfuls and sweep them into the basket. Then 
remove them to the brooder or .brooder house. The temperature of the 
brooder or brooder house should be near ninety degrees. The food and 
water should be already in the brooder before you put the little ducklings 
in from the incubator. They will be hungry and will go to eating and 
drinking at once. 
Youngest Ducklings 
You have allowed the ducklings to stay in the incubator twenty-four 
hours after they have come out of the shells. They are double the size 
of a chicken, and in appearance about twice the size of the egg-shell 
which enclosed them. 
A period of twenty-four hours in the machine dries them so that 
they are strong enough to stand on their feet. They 
have absorbed through the navel the yolk which sur- 
rounded them at birth, and this sustains them for the 
twenty-four hours. : 
At the end of the twenty-four hours put them into a basket and carry
