I'm slightly confused by your weights (it doesn't take much!).
Assuming you have Goldies, I'm guessing they would weigh between 30-35 kgs (as mine do)? They get about 1lb (454g) of meat a day + meaty bones, which are lamb ribs, maybe 3-4 times a week. I don't feed chicken bones, other than in minced meat, because mine tend to swallow them whole and I often saw fragments of bone in the poo, which I don't with the lamb ribs. If you want to feed chicken bones I'd feed larger pieces or something like half a chicken that can't be swallowed in one hit and he has to work at! Mine get occasional extras such as eggs, pulped vegetables and leftovers, yoghurt etc.
Some people make the change from kibble to raw straight off, others take it more slowly. I guess it depends on your dogs. My lot went from Naturediet one day to raw the next with no problems at all.
