I have alfalfa hay here for the horses. Would the roos eat it is I tossed some in with them? I read that they eat plants and greenery and am wondering if they would like this.. there is so much to learn! Another thing: I know that they like to scratch around for their feed. I have a bird feeder type of thing I was going to use (holds it in a metal grid-type tube thingie and it falls into the little tray at the bottom as it is eaten.) Is it better to just toss the feed on the coucrete for them to scratch, or fed in feeder?
