Set a custom dafault date for a nullable date column on Laravel

I want to set a default date of 1900-01-01 on a nullable date field.

I've tried this

$table->date('fecha_nacimiento')->nullable()
    ->default(\Carbon\Carbon::make('1900-01-01')->toDateTimeString());

Also

$table->date('fecha_nacimiento')->nullable()
    ->default(\Carbon\Carbon::make('1900-01-01'));

Also

$table->date('fecha_nacimiento')->nullable()->default('1900-01-01');

When I save from the browser with the HTML date input not set, it saves the date field as null.
