If cooking more than one chicken at a time take longer just one?

It depends on the cooking method.

For oven baking: Cooking multiple chickens at the same time will generally increase the total cooking time. This is because the oven has to work harder to heat up and maintain a consistent temperature with multiple chickens inside.

The amount of additional cooking time needed will vary depending on the size of the chickens and the oven's capacity. As a general rule, you can expect to add 10-15 minutes per additional chicken.

For example, if you are baking two chickens at once, you might need to cook them for a total of 90 minutes, whereas a single chicken would only need 75 minutes.

For stovetop cooking: Cooking multiple chickens at the same time can actually reduce the total cooking time. This is because the heat from the stovetop can be distributed more evenly among the chickens, allowing them to cook more quickly.

The amount of time saved will depend on the size of the chickens and the number of burners available. As a general rule, you can expect to save about 5-10 minutes per additional chicken.

For example, if you are frying two chickens at once, you might need to cook them for a total of 45 minutes, whereas a single chicken would need 50 minutes.

Tips for cooking multiple chickens at the same time:

- Use a large enough baking pan or skillet. The chickens should not be crowded, or they will not cook evenly.

- Preheat the oven or stovetop to the correct temperature. This will help the chickens to cook evenly and prevent them from drying out.

- Turn the chickens halfway through cooking. This will help to ensure that they cook evenly on all sides.

- Use a meat thermometer to check the internal temperature of the chickens. They are done cooking when the internal temperature reaches 165 degrees Fahrenheit.
