I will agree with you there.
I have a bit of OCD or whatever you want to call it. I build all my racks single file now. I also replace my animals one rack at a time. It just makes things simple for me.
Suzuki, I know you know what I am talking about when I say that the same stuff that you used to do when you had one or two racks just doesn't cut it anymore when you have more than a dozen racks.
I have a system in place now that accounts for the timing between holding animals back, growing animals out, and replacing animals before they start to decline in production.
