I'd also be interested in the answers to the above post.

Novel protein and novel carb. But introducing to all of these proteins could prove to be a big problem later (or sooner rather than later). Giving a few different kinds of protein is fine, but switching it up so much can leave you in a spot if an allergy does develop. You'll have nothing novel to go to. In other words, choose several that you don't give to save in case you have to use them someday.
