There isn't an animal dealer even though the icon is there. It will be coming in V2. The straw trigger on the big freestalls is right down the middle and I believe it is a bale trigger. Double check you own the land the pasture is on and check all of the gates being that's where the triggers are located.
tried to use a bale blower but for whatever reason the bale blower doesn't recognize there is a bale in nor will it turn on. Most difficult map to use straw on. Going wait for v2 and see if I can make anything work on that. Please consider making the barns so they can be demolished. I would put barns in that I know how to work but I can't remove the old ones. Thanks!
