Same thing has been happening to me on iOS version. As soon as I upgraded to deluxe barn and coop, all the animals starting loosing happiness. Couldn’t figure out why and it appears that everyday, the silos aren’t changing the amount of hay. Currently in winter, animals aren’t grazing outside. Hay troughs are always full but when I check silos they aren’t going down.
I had read on a different forum that blowing up the hay (so you can pull hay out of the silos) and then manually removing it all and then putting back, didn’t work. Blowing it all up and leaving it overnight to auto fill, works to auto fill but then the next day same thing happened where no new hay has been removed.
I keep trying different things and it seems I’ve been able to get the deluxe coop to work as the animals happiness is back up to max. But the barn is still not working. Each day only few hay have come out of the silos, but not enough for all the animals I have.
I haven’t yet tried moving animals to a new barn and back. Or filling the barn and coop to max animal capacity. Currently barn has10 and coop has 10.
