I purchased a buck and will be picking him up in the next few weeks. I built him his own pen but I had to till it up and reseed it. So there isn't much grass in there and it wont be fully grown in by the time I get him. I don't want to risk having UC problem. So what should I feed him? I read in another post about vitamin c...where do I get that and how much do I feed? I currently have 2 wethers that will be with him...and I've never penned them...they roam around and browse...I do not feed them anything and have never had a problem but while penned with the Buck they will also need something to make up for the lack of grass until it grows...should bucks and wethers be fed differently?
