I would like to suggest a feedbin for neighborhood blocks, that cannot be picked up, like the machines.
-Could hold more than a typical Piggy Feeder
-Feed couldn't be removed from it
-Built using Blockmaking, or
-If Staff were feeling extra gifty, could be added to new developments for free.
-Meat/Milk Collectors on common streets would still not be allowed.
Reasoning:Today, I stocked my neighborhood with many, many piggies (78) and chickens (56), and laid down 250 grain in each block so that they'd be fed for quite awhile. A few hours later, I came back to find a lot of the grain missing. A staff member in Live Help has assured me that it wouldn't have disappeared on its own, so someone's taking it!
I also just found a note saying that "grain doesn't feed pigs anymore, but feel free to leave crops!" After putting down 4-5000 grain, and the aforementioned livestock, all for free - I don't feel like it.
I live out in Andra, and we don't have trees in our neighborhood blocks - so the piggies will starve if food isn't left out for them!
