Have any of you had any problems with it lately? We just swapped over to it a couple of months ago. At first the horses were eating it real good. Then we noticed some bags had some bird seed looking stuff in it and the horses didn't eat it as well. Well, last week we went and got a ton of it as usual. The horses will not eat it at all. We don't see any of the seed looking things, it doesn't smell bad - but they won't eat it. We opened several bags to see if it was just one or two bags that were bad - but not one horse will eat any of it. Dad called the Nutrena place and talked to a man there. He said that he had had other complaints of the bird seed. He said they had a new mill they were using in Louisiana and that they had already discussed that issue with them. He said it was weird that they wouldn't eat the new bags though. A few hours after that conversation, the guy called back and said a big farm down in Florida had called in to, also complaining that the horses would just not it the food and that they had been eating it fine. So they are sending in a truck from another mill with another ton and they are going to bring it to us and pick up the other bags. Have any of you, that feed Nutrena, had any problems?
