Then we took two screens of half-inch wire mesh and fitted them on a ledge of 1 x 2’s laid on the edge at the incubator’s bottom. An aluminum pie plate was placed on the floor to serve as an evaporator tray. We cut a lid to fit from scrap lumber and lined both the antique crate and its cover with heavy-duty aluminum foil to provide reflection of internal heat. While we waited for the thermostat to arrive, we lugged down from the attic a deep wooden packing case that had contained bottles of a one-time popular soda beverage called Clicquot (“pronounced Klee-Ko,” we were told by the lettering on the box). This was our only piece of store-bought equipment. First - because accurate temperature control is vital - we ordered an electric thermostat switch. It was inexpensive to construct, isn’t at all elaborate and - while far from ideal - gives good results with careful attention and maintenance. The mini-hatchery we built to increase our flock is of the convection type. Again, care must be taken to maintain proper humidity. Incubators of this type are also vented, but air and heat are circulated with a fan instead of by convection.
This means that relative humidity must be maintained by the use of evaporation trays and carefully monitored with a device called a hygrometer. The disadvantage of this method is the higher rate of evaporation created by the air currents. Placement of the eggs and the thermometer are thus much less crucial than in the still-air machine.
It’s then warmed by radiation and circulated around the interior.
The upward draft in the chamber causes fresh air to be drawn in at the base of the device. This type of incubator has ventilation holes in the top and bottom to provide a continuous flow of fresh air and an even distribution of beat. The air must be flushed thoroughly from the apparatus at least four times a day (when the eggs are turned), to release the noxious gases that accumulate in the closed box. A wrongly positioned instrument will be inaccurate by several degrees - enough to cause the failure of the hatch or the death of any chicks that do emerge. It’s also just as important to locate the thermometer correctly. Still-air incubators are warmed by uncirculated radiant heat, and the placement of the eggs in relation to the heat source is critical. There are three basic types: Still-Air Incubators MOTHER.)Īn incubators is a device that provides controlled conditions for the hatching of eggs. (A mature layer of one of the maternal-minded heavy breeds will manage the job quite nicely but she’ll pick her own time, and it probably won’t be as early in the spring as you could wish if you’re in hurry to establish a productive flock If your chickens are leghorns or one of the other light types, you’ll probably need an incubator in any case to compensate for their lack of motherly feeling. We could find no information on incubation of the eggs, not even under a broody hen.
HOMEMADE EGG INCUBATOR COOLER MANUALS
The only trouble with this idea was that all our books manuals and brochures on poultry-raising told us to begin with day-old chicks. That’s when we decided to try hatching our own fertile eggs. Then spring rolled around again, our neighbors began ordering new chicks from the hatchery and we discovered that the cost of day-old biddies had doubled in our area. Meanwhile, meat prices were rising steadily and we began to consider keeping more chickens for slaughter. By the end of each week during that period, we always had at least a dozen extra for sale or gifts to friends. Five months later we discovered our first egg, and gathered the fresh, fertile layings faithfully each day for many months afterward.
We clipped their wingtips at that point, constructed a broiler house from miscellaneous scraps of wood and wire and - when they were sufficiently grown - moved our birds to their outdoor quarters. By the second week the babies’ wings had developed and we discovered them flying around the room and alighting on various objects. The day-old chicks were carefully tended, kept warm and protected from drafts by a homemade brooder - a cardboard carton heated with a light bulb - in our empty guestroom for a few weeks. Our start with chicken-raising was very cautious: a tiny flock of ten pullets and a cockerel, obtained from a hatchery.
