Drupal features recreate issue with CCK fields
I faced the same issue today. After a lot of searching, I found the following patch.
https://www.drupal.org/node/2210241

I was able to solve this using the patch provided.
Can export the conditional field settings (along with content-type &amp; fields) in a feature.
In my case the dependent is a Date field &amp; dependee is a boolean field.

Conditional field 7.x-3.0-alpha1
features 7.x-2.2
