Anyone ever dehydrate  their own chicken?

I have.  Though I think the foil packet chicken is a better option.  I dehydrated before the foil packed chicken was available.

If so:
What type of chicken did you start with?

I've done it two ways.  First I made chicken jerky made of skinless chicken breast (cooked first).  The other way was to use Swansons canned, white, chicken. If you're going to rehydrate, I strongly recommend using the canned chicken.

Unlike beef, it is vitally important that the chicken is cooked before dehydrating!!!  Canned chicken is already cooked.

How did you do it (dehydrator, oven, or other)?

I used a dehydrator.  Dehydrate just like you'd dehydrate beef jerky.

What setting did you use on the above appliance?

I don't know.  Again, like beef jerky.

How did the chicken rehydrate (hot or cold water, how long)?

I rehydrated in warm water for perhaps an hour before I start the recipe.

How would you rate the quality of the end product?

Chicken jerky is fine, but I don't think it is worth it.  I much prefer beef or venison jerky.

As far as using it rehydrated, it was edible but somewhat rubbery.  As I said before, I'd opt for the foil packets and not use dehydrated chicken.

What sorts of meals do you use it in?

The rehydrated stuff I used in Chicken Helper.  Foil packet chicken and Chicken Helper is the way to go now.
