Its up to you what you feed (within reason as it must be balanced) but all mine are fed all types of bones including my latest addition baby Rott, who was weaned on raw meat n wings and we continued when she came to us at 8 weeks. She has lamb ribs about 3 times a week with no problems altho she does eat them fast so I give her space from the others so she knows she can take her time.
Does he gulp them down and not chew them properly? Is he the only dog at home, does he feel he needs to eat them quickly so another dog doesnt take them?
Chicken bones are not hard, they are bendy when they are raw. I feed all the carcuss and necks too. If you are worried about him not getting the bone content, you could always feed raw minced chicken as this has a high bone content.
If it were me I would try to be a little braver! :-)
