## Abstract

A method for incubating avian eggs, comprising: a. introducing avian eggs into an incubation chamber having an oxygen-containing atmosphere; b. subsequent to ‘a’, incubating said eggs in said incubation chamber for a period of time that is not less than 25% of the natural incubation period of said eggs; c. during said period of time of the incubating, changing an orientation of said eggs at a frequency of not less than once every two days; and d. during said period of time of said incubating, varying a temperature of said atmosphere in said incubation chamber at a frequency of not less than five times a day, the varying comprising: increasing the temperature of the atmosphere from a first temperature to a second temperature, the difference between the first temperature and the second temperature being not less than 1.0° C.; and reducing the temperature from the second temperature to a third temperature, the difference between the second temperature and the third temperature being not less than 1.0° C. wherein the rate of said increasing the temperature of the atmosphere is not greater than 0.9°/5 minutes; and the rate of said reducing the temperature of the atmosphere is not greater than 0.9°/5 minutes.

## Claims

### Claim 1

A method for incubating avian eggs, comprising:
a. introducing avian eggs into an incubation chamber having an oxygen-containing atmosphere;
b. subsequent to ‘a’, incubating said eggs in said incubation chamber for a period of time that is not less than 25% of the natural incubation period of said eggs;
c. during said period of time of the incubating, changing an orientation of said eggs at a frequency of not less than once every two days; and
d. during said period of time of said incubating, varying a temperature of said atmosphere in said incubation chamber at a frequency of not less than five times a day, the varying comprising:
increasing the temperature of the atmosphere from a first temperature to a second temperature, the difference between the first temperature and the second temperature being not less than 1.0° C.; and subsequently
reducing the temperature from the second temperature to a third temperature, the difference between the second temperature and the third temperature being not less than 1.0° C.
wherein the rate of said increasing the temperature of the atmosphere is not greater than 0.9° C./5 minutes;
wherein said reducing of said second temperature to said third temperature commences after a period of at least one minute subsequent to attaining said second temperature; and
the rate of said reducing the temperature of the atmosphere is not greater than 0.9° C./5 minutes.

### Claim 2 (depends on 1)

The method of claim 1, wherein the avian eggs are of a species of bird selected from the group consisting of chicken, turkey, goose, duck, pheasant, quail, pigeon, partridge, dove and ostrich.

### Claim 3 (depends on 1)

The method of claim 1, wherein the avian eggs are chicken eggs.

### Claim 4 (depends on 1)

The method of claim 1, wherein said temperature difference between said first temperature and said second temperature is not less than 1.5° C.

### Claim 5 (depends on 1)

The method of claim 1, wherein said temperature difference between said first temperature and said second temperature is not more than 5° C.

### Claim 6 (depends on 1)

The method of claim 1, wherein said temperature difference between said first temperature and said second temperature is not more than 4° C.

### Claim 7 (depends on 1)

The method of claim 1, wherein said second temperature is not less than 37° C.

### Claim 8 (depends on 1)

The method of claim 1, wherein said first temperature is not greater than 37° C.

### Claim 9 (depends on 1)

The method of claim 1, wherein said varying of said temperature of said atmosphere is at a frequency of not less than ten times a day and not more than twenty-four times a day.

### Claim 10 (depends on 1)

The method of claim 1, wherein the rate of said increasing the temperature of the atmosphere is not greater than 0.8° C./5 minutes; and the rate of said reducing the temperature of the atmosphere is not greater than 0.8° C./5 minutes.

### Claim 11 (depends on 1)

The method of claim 1, wherein the rate of said increasing the temperature of the atmosphere is not greater than 0.7° C./5 minutes; and the rate of said reducing the temperature of the atmosphere is not greater than 0.7° C./5 minutes.

### Claim 12 (depends on 1)

The method of claim 1, wherein the rate of said increasing the temperature of the atmosphere is not greater than 0.6° C./5 minutes; and the rate of said reducing the temperature of the atmosphere is not greater than 0.6° C./5 minutes.

### Claim 13 (depends on 1)

The method of claim 1, wherein the rate of said increasing the temperature of the atmosphere is not greater than 0.5° C./5 minutes; and the rate of said reducing the temperature of the atmosphere is not greater than 0.5° C./5 minutes.
