I use Holistic Select too (the fishy one) and the dogs seem to do good on it. Hamish grew up on the large breed puppy one. I hadn't heard of beet pulp being a problem before though. I think most holistic foods have it.
If you think they should be getting more egg though I don't see why you couldn't give them more once in a while. I add sardines and tuna each week to their food (because Shar Pei's need the extra fish)
