So you leave a couple of porks in the pen and put some carrots in the feeding through and it gives them to eat a couple times and then it stops,

As an added suggestion it is cool to have a some sort of limit to the animals, like don't feed them when we have 10 or something but this is just not the case here.

Also what is the range for the feeding, because my pen is small, like 4x4 and the feeding is in the middle the animals are moving around but the amount of animals never grows.

v.1.12.2-3.1.12

could it be that it only feeds each animal once and that's it?

my bad just found config for 5 animals! duh!
