Hi Tides:

http://dogaware.com/diet/freshfoods.html

Here’s a nice article on adding fresh foods to a commercial diet.
I’m not sure if your dog could tolerate eggs since he’s so allergic to chicken. Personally, I wouldn’t risk it. I wouldn’t concern myself with the variety needed for a stand-alone raw diet if he’s still getting some commercial foods.
Beef bones aren’t the best option for consumable bones, however letting him gnaw on bones would help keep his teeth clean. The only dogs around here who don’t get recreational chew bones (beef bones) are those who chew aggressively, so much that chipping teeth is an issue.
Though I don’t feed it a lot, green beef tripe is an absolute hit in this house and the acidic nature helps keep their teeth clean, as well as all the great enzymes helping digestion. As long as the butcher gets it from a good source, I’d take him up on his offer, it sounds great!
Hope this helps get your plan off the ground!
