I know you can hit chicken and then loot them but strangely I can’t hit them. Does anyone have the same issue? Why is that?
There are groups of chicks you can hit, and another you can´t. Test this in Skalitz (start town).
But sometimes the game crash if you loot chickens. And I think there is a bug you can´t eat/cook chicken meat,… not sure. 
Try punching, is harder with sword. Not impossible but harder.
Ok didn’t know there are different ones. I tried hitting them in Skalitz at the beginning but it seems like I always tried to hit the wrong ones. So that means when I see chicken I just have to try out which ones I can hit and which not, right?
Yes, but attention… it could be a crime… 
Now I’m getting skyrim vibes haha. Anyway thanks.
