Thank you for the responses!
To clarify, does the breeding cooldown only trigger on successful breeding or every time (if fails, do we have to still wait that hour for a retry)? And does the female's cooldown start after breeding or after giving birth?
On a separate note, I didn't realize just how crazy cows were - 60 milk buckets an hour lol XD I thought it would be more like 1-2 buckets a default day so I would need a herd for tons of milk. Guess I just need dear ol' Bessie. I'll probably swap to goats /sheep for milk balance if they produce less once they are milkable, so I can have a herd feel "useful".
Thanks again!
I'd rather it be changed so they produce way less.
