Kibble and raw meat are digested at different rates and it is often recommended that there should be 12 hours between the two. It very much depends on the dog. My cocker adapted to a complete BARF menu without any tummy/bowel upset almost straight away but my older dogs took quite a bit longer and had to be done at a slower pace.
There are people who continually part feed BARF and part feed Kibble, particularly if your dog is likely to go into kennels. I haven't come across a kennel yet that will feed BARF!
There is often confusion with chicken bones. You must never feed a dog cooked chicken bones. Cooking makes the bones brittle and therefore they could splinter causing damage to your dog. However raw chicken bones are ok to feed your dog. Until I started raw feeding I'd not got intimate with chicken bones but I discovered that I (confirmed weakling) could snap a wing bone.
Like was said earlier I had 50 fits when I first fed a wing to Barney, I even fished it out of his mouth half way through eating it.
I panicked.
Five minutes later I took a deep breath and gave him it back and he was fine.
It is perfectly possible for a dog to choke on a piece of kibble, in the early days I kept that fact in mind!
I struggled with amounts in the beginning and had a lot of help from my marvellous friend RhonaW who had swapped to BARF a few weeks earlier.
A couple of key facts; a dog does not need to get everything he needs nutritionally in the space of a day look to do it over the space of a week.
Secondly on how much to feed. Books give you basic ratio's which are a good starting point, after that its as simple as if they are getting a bit skinny feed them more or if they are getting a bit weighty feed them less.
If I think of anything else vital I'll come back!
