I'm new to this site as well as raising chickens. Just got my first 15 the other day. Already dealing with Pastey Butt and have read many different opinions on what works best. I didn't have any yogurt this morning (will get some this afternoon) but I did have two hard boiled eggs so I ground them up and put them in their little pen. I haven't a clue if it's enough or to much. Any advice is welcome!
