40 POULTRY SECRETS REVEALED. 



Another cause of failure is in buying the worthless so-called 

 "incubator" eggs — the sort that costs from two to four dollars per 

 hundred. It is an insult to the machines to fill an incubator with 

 such trash. Unless you can afford to buy enough good eggs to 

 fill the machine you better depend on hens. For the best and 

 freshest eggs should invariably be used in machine hatching. 



Hot air and hot water machines are both used Under proper 

 conditions either will give satisfaction; under improper conditions 

 neither will do so. 



A close, ill ventilated room is the worst place for an incubator. A 

 well ventilated cellar is the best. 



And don't be timid about cooling the eggs. They need it. 



Don't use a turning tray. Turn by hand. A quarter turn is enough. 

 But do it three or four times a day. 



And finally, bear in mind that the eggs must have fresh air. This 

 does not mean that a current of air should blow over the eggs; for 

 that would dry them out and ruin the hatch: but it does mean that 

 pure fresh air must reach the eggs if they are to hatch and the chicks 

 are to thrive.
