A neighbor came and spoke with me while I was feeding Cinder (I seem to have a very nosey neighborhood lol) and asked what I was feeding. I said her grain was a mix of Nutrena Safechoice and alfalfa pellets, and her hay was very good quality alfalfa/orchard grass mix.
He asked if Cinder was getting diarrhea from it and I said no, her poops were perfect (as horse poop goes) and he said in his experience alfalfa always caused diarrhea.
I haven't heard of it before but I'm curious, does alfalfa give diarrhea? Why?
