Custom Fields not populating with default value

Custom Fields not populating with default value

I have an additional field defined as type pick list with values Yes or No. The default value defined is "No" however when new incidents are created they are not receiving the default value, they are blank.

Do I have to make the field mandatory on the template/form for it to populate a default value? That is the only thing I can think of, we were hoping to not make it mandatory as some of our group needs to use this field and others will not but we always wanted new incidents to be created with a value of NO for this additional custom field.

Thanks,
