How much to feed?

We hang it for a few days before skinning and processing.(depending on temperature) It allows the meat to cool, and it's easier to get the hide off and cut up for washing and wrapping.

ill stick with the grocery store.

Im trying to feed Olaf raw/domestic food. Firts 2 days i gave him quality kible, he didnt really like that, and would leave cca half a fist of food each meal (i feed 2X a day). He was pretty skinny when he came, and he even got skinnier here.
Here is what he has been eating last 2 days (is that enough food for him?):

yesterday evening

(to get the feeling about the size, the pinky thing in the middle is chicken neck)

4-5 chicken necks
1-2 handfulls of chicken stomachs
2 slices (dark red stuff) of bovine heart
1 slice of bovine kidney
cca spoon of olive oil
brown thing is leftovers from morning meal (cooked chicken, rice, veggies)

Today morning
2-3 handfulls of chicken stomachs
3-4 chicken necks
1 whole egg raw

Today evening
4-5 chicken necks
1 can tuna cca 180g
cca one small human portion pasta with sauce

Is that too much chicken necks?

Btw, according to picture on the first page, he is number 3
