Bison Food Enrichment

[TunaSammy]

I love myself some bison! However, I'm having a hard time keeping a big herd happy with the available food enrichment items. Am I missing something? I hate to just throw a ton of the same enrichment items in.

at least you can change the color of some of the items so you don't have to look at the same green feeder barrel all over, can have them in a rainbow of colors lol

Click on an animal. Look at its welfare stats. It will say if the food it is getting is of a suitable quality. There are 3 grades. (And for no apparent reason after around 30 years the game decides they need a higher grade.)
Also, as your keepers become trained they can look after the animals better.
But yes, the more animals you have in an enclosure, the more feeders you need. Stats will tell you if you have enough. You also have to research better feeders.
