Looking back over the memories of my farm initiation, it seems as if I had not fully realised the possibilities of my new undertaking until the first incubator was inaugurated. As I have already told you, I did all the first year’s hatch under hens, and still set every hen that evinces any desire to assume the cares of motherhood, because it seems Nature’s plan to keep the egg machine in good working order. If a broody hen is not allowed to sit, it takes several days of incarceration to break up her desire, then several days more after she is freed before she commences to lay, and invariably the sitting fever will attack her again within a few weeks. Now, incubation takes only three weeks; brooding of chicks, another four or six weeks, and Mrs. Biddy has had a complete rest, followed by vigorous exercise while scratching for her babies. So when she is returned to the yard she is in perfect condition to produce eggs. Let Biddy sit whenever she wants to, but don’t wait her pleasure in the early spring, for you might have no young chickens to sell when they bring good prices. THE SELECTION OF THE INCUBATOR There are a great many incubators on the market, some heated by hot air, others by hot water. If you select any one of the standard makes advertised you will get a good, practical hatcher. Printed instructions for setting up and running are sent out with every machine, but they don’t emphasise all the important points quite strongly enough for amateurs. Lots of people can’t drive a screw home accurately, and fail to realise that if the head is slightly to the right or left it throws the fixture which is being attached to the machine out of plumb, and a hair’s breadth makes a difference when such delicate appliances as thermostatic rods (the power which controls the heat), are concerned. A blunder supplies much knowledge. I should never have realised the necessity for absolute exactness if one of the screws used in attaching the lamp support to our second incubator had not gone slightly awry. It caused the chimney almost to touch one side of the socket into which it fits. That, in turn, drew the flame to one side, and caused it to smoke at night when turned up for extra heat. It was a very little blunder, apparently, but it almost spoiled the incubator, and quite spoiled the hatch.
