I heard it was possible to overtax a chicken to death by having it incubate a gazillion times in a row. But don't quote me on this! I haven't done it myself.
I thought they eventually go away when they've been squeezed enough, so maybe have a grain gathering party? Higher AK skills can get more grain, by the way. I think now that I'm on AK 6 I can get 25 from a chicken before it refuses me.
it wasn't me this time! I say this as I was experimenting in Doon Way on animal ratios a few days ago and managed to make all the chickens sad. They were lying on the ground moaning about unhappy they were. I felt bad(ish) but when I went back a few game days later, a few of them had flown away so it should sort itself out eventually.
I find the chickens to be mostly annoying..They need to have further uses built in...How about actually being able to have chickens lay eggs???
Limits to how many animals per street shoudl be a definate..No more than 6 animals of each ona street would keep things less hectic..
