What weight in kilos is a size 28 chicken?

You can't determine a chicken's weight in kilos based solely on its size "28."

There are a few reasons for this:

* Size "28" is not a standard measurement for chickens. Chicken sizes are often described with terms like "broiler," "roaster," or "fryer," which relate to their age and intended use.

* Chicken weight varies widely within the same breed. Factors like genetics, diet, and age influence a chicken's weight.

* Different regions and countries use different size classifications.

To find a chicken's weight in kilos, you would need to know:

* The specific breed of chicken.

* The age of the chicken.

* The weight range for that breed and age.

You can often find this information from poultry suppliers or online resources dedicated to chicken farming.
