If there's anyone around who can answer these questions, they'll get a cookie...
Pregnant females vs. barrel of milk: Will calves always drink milk out of a barrel, or is there some position relative to the mother cow where they'll prefer it over the barrel? Is it maybe q-dependant?
Pregnant females of non-cow species: Is there some way of detecting their ability to give milk, or is this impossible?
Pregnant females feeding different species: Does it work to feed young pigs / sheep from a milk-giving cow, or from a barrel of cow's milk? From my experience, barrels work with every species, is this assumption correct? Can pigs feed sheep, cows?
Feeding radius of females: How many tiles? Same as food troughs?
And here, an easy one:
Food consumption per .1 l of milk given of cows? (jorb posted it once in C&I, dont wanna read it up now)
