Hi, I don't have experience with feeding a raw diet, but I do have experience with allergies. Many EBs are allergic to chicken, and will show the same symptoms that you describe. Goopy eyes, itchy paws, yeasty ears, excessive licking of paws are all signs of allergies. The only way to determine what is causing the allergies is by trail and error, and elimination. You won't know what he's allergic to until you try different proteins and see which ones aren't tolerated.
Turkey, duck, or other birds may also cause a reaction, or you might try fish or beef instead. You can get calcium from crushed egg shells. Put the egg and shells in the food and crush the shells really fine, they are a good source of calcium.
