We feed twice a day with some treats in between, though breaking it into three meals seems to help a lot when first starting out. They get raw chicken backs/legs/wings in the morning with a bit of Greek yogurt and rice. The current favorite treat is raw chicken feet.
In the evening they get their glop, which is a mix of ground beef, beef kidney; chicken heart, gizzard, and liver; chopped mackerel; eggs with shell; and produce (mostly greens with broccoli, carrots, cauliflower, pumpkin, and berries). I puree the kidney and liver with the eggs and produce so it gets mixed in well (this has helped tremendously with loose stools due to offal), and all the meats and produce/offal/eggs are mixed together. I try to make a big enough batch to last for 3-4 weeks. We put several days worth in a container in the fridge and freeze the rest in several big bags. This mixture is also served with a bit of Greek yogurt and rice.
