No, it would not be too much fish with added sardines. Just like it would not be too much chicken if you added some real chicken as a topper for a chicken kibble. As far as the large portions are concerned, that’s where a big freezer comes in handy and a grinder. You could purchase various meaty bones and cases of organs and muscle meat and then use them according to the recipe you choose. X lbs of necks, X lbs muscle meat, X lbs organs, etc. Or you could start with a Premix where you only add in muscle meat (ground chicken or beef or pork, etc) and the Premix and some oil. The Premix has vitamins. When I order by the case, I prefer 2 lb chubs over 5 or 10 lb chubs but I have small dogs.
