We had chickens for a few years when I was a kid. They are needy and not very cuddly. They are also seriously lacking in brains. The chickens we had were there primarily for eggs and, occasionally, dinner. I am delighted to have them in my game, but my sims are not making friends with them, at least for now. I'm too busy laughing every time the fox gets into the chicken coop. Love seeing those feathers fly! >:)
Edited to add: I don't know how I'll feel once the fox actually gets a chicken. By keeping them at arm's length I hope it won't bother me.
