You can get the field like this:

myfield = MyModel._meta.get_field_by_name('field_name')

and the default is just an attribute of the field:

myfield.default

TheModel._meta.get_field('the_field').get_default()

As of Django 1.9.x you may use:

field = TheModel._meta.get_field('field_name')
default_value = field.get_default()

if you don’t want to write the field name explicitly, you can also do this:
MyModel._meta.get_field(MyModel.field.field_name).default

If you need the default values for more than one field (e.g. in some kind of reinitialization step) it may be worth to just instantiate a new temporary object of your model and use the field values from that object.

temp_obj = MyModel()
obj.field_1 = temp_obj.field_1 if cond_1 else 'foo'
...
obj.field_n = temp_obj.field_n if cond_n else 'bar'

Of course this is only worth it, if the temporary object can be constructed without further performance / dependency issues.
