What does Livestock feed in ranches actually do?
The wiki says it "fattens them up", but what does that mean? Does it increase corpse quality? Or corpse quantity once killed? Or produce (milk/eggs or body parts) quality/quantity?
It'd be useful to know to decide if ir's worth the hassle or not.

Also, best ranch animal for valuable eggs? Wiki says the beast's weight produces heavier eggs which are worth more, but what's the best monster in terms of breed power/egg weight ratio? Or shouls i just go Chickens because they produce more? Finally, do cooked eggs worth keep their weight-dependant monetary value?

Sorry for the many questions, but i couldn't find good answers with my google-fu.
