When I brought Fannie out to the barn I told the woman who feeds that she doesn't get daily grain where she came from and she didn't really need any. (Fannie is a cow!) I told her to give Fannie a handful (I literally cupped my hand and showed her how much.) if she was throwing a fit when the other horses were being fed. She said ok and I didn't think anything of it after that.
Well, a few weeks later she admitted to me she had accidentally given Fannie a half scoop that morning because she wasn't paying attention. No big deal accidents happen. She then showed me how much she had been giving her everyday and it was a QUARTER SCOOP. Fannie is a hot horse and they feed sweet that is a no go. So after that I picked up the amount of grain Fannie could have to be clear and put it in her bucket.
I've since then decided Fannie needs no grain at all and bought my own bag of complete to feed on days when she has a really hard work out. But I still think the feed woman is dropping grain to Fannie. I keep seeing little remainders of what looks like sweet feed in Fannies feeder. (I don't feed her in her stall.) The woman who feeds has told me on several occasions that she "feels bad for her".
