Kitten's first chicken wing - Does bone digest?

I heard that chewing on raw chicken bone is good for a kitty's dental health, and thought it'd be great to give my kittens a chicken wing (the wingnette [?] part, the two bones joined together) once a week or so, rather than do a terrible job at trying to brush their teeth. The idea of a raw homemade diet feels a bit overwhelming at the moment, but I feel good about feeding them a raw chicken wing once in a while.

I fed them their first wing today. I cut most of the meat off and mixed it into their wet food, and left some meat and fat on the bone for them to chew. Both of my kittens ate up the wet/raw food right away without hesitation. The younger one, CC, had no idea what to do with the bone and didn't go near it (I think it may look too big for her). The other one, TT, loved it, and was very protective of it as she was eating it (CC came closer to sniff what she was eating and she growled her away as she was gnawing, lol). To my surprise, she swallowed half a bone right up. The swallowed bone may have been around a good 1.5" long. She diligently chewed up the rest of the wingnette bit by bit. And then, because CC wasn't eating her portion, TT ate hers up too. But she did a similar thing where she swallowed up another longish piece of bone, and this one looked a tad pointed because she had chewed the bone in half before swallowing it.

Should I be worrying about intestinal blockage or her insides potentially getting punctured by these larger bones? She's currently 17 weeks old, around 4.5lbs, and swallowed those bones with ease. Would she be pooping out those bones whole, or would they somehow break up and digest a bit before coming out? Also, I'm wondering if that was a bit too much calcium? I'm not sure how much calcium is too much or just enough for a kitty (She already eats around 2 tablespoons of plain unsweetened/no-additives yogurt a day because she really likes it and to aid her digestion.).

Well, my cat pooped. I suppose all is well. Both my kitties were very energetic yesterday night and this morning too, for much longer than their already energetic kitten selves. So, I think I'll keep up a once-a-week chicken wing treat I can't seem to figure out the calcium stuff though, and in my research, a calcium-to-phosphorus ratio keeps coming up, it's kind of making my head spin, lol.

Kittens can handle the smaller part of the wing with ease. They will digest the bone just as they digest the other food.
A wing once a week makes a nice treat; you will know if that is too much if the cats' poop is really hard or, of course, if there is any blood.
Yeah, calcium : phosphorus ratio makes my head spin too.
I fed prey model raw ("frankenprey")--a combination of meat, a secreting and non-secreting organ, and bone. I would not be too concerned about the C ratio unless I would / couldn't feed bone for some reason, i.e., cat simply won't 'do' bone or an underlying health issue (kidney problems). I rotate at least three meat/proteins, and hope-trust it all balances out.
