This is my first real buck that I've kept. I've always just "borrowed" a buck for a few weeks previously. So I have him in an electro-net area that's full of grass. I can't drylot him, and I want him out on fresh grass anyways. However, I want to make sure his Calcium/Phosphorus ratio stays in balance because I'm afraid of Urinary Calculi. He has a hay net full of 1st cut grass hay as well (which of course he doesn't touch because he's got an area full of grass). He has two water buckets that are refilled every day and I just recently added a white salt block. I'm going to put the MannaPro Goat mineral out for him as free choice as well. Do you think I'm overdoing it? What is the Calcium/Phosphorus ratio (generally) for fresh grass? I just want to make sure I'm not giving him too much or too little or anything.
