Great idea to start a thread on this to have all the info in one place.
I make dehydrated chicken breast treats, not technically jerky.
I buy chicken breasts from Costco, and bake them at 425 F in the oven for about 20 minutes until they are cooked completely through. I cool them in the refrigerator. Once they are cold, I slice them into 1/4" thick slices, and lay the slices in the dehydrator. I use the dehydrator on the hottest setting, 160 F, and it usually takes about 4-6 hours to dry the chicken, depending on how many trays I fill. I rotate the trays partway through, a couple of times.
Once the chicken is dehydrated, I store it in freezer bags in the freezer and only defrost a handful at a time. I store the defrosted pieces in the refrigerator in an airtight container.
My dogs get a piece after grooming, nail clipping, ear cleaning, baths, etc. They love them! They have never gotten the runs from my homemade chicken treats!
