I feed about 5 quarts of grain twice a day, total of 10 quarts and I have one of those buckets from walmart, pictured below ( not my horse by the way in the pic). I fill that bucket up with hay twice a day and feed that as well. I was at a friends house today and he says he feeds his about the same amount of grain that I do but as for hay and how he measures, he gives his about 16 pitch fork scoops of hay twice a day. Tonight when measuring my hay, I used the fork and I was able to get about 8 scoops in that bucket and it was jam packed. I took it and put in the trough, which is about 2 1/2 ft by 4 ft and it is about 8 inches deep. It pretty much fulled the trough. I did get 2-3 more scoops with the fork and put in the trough. The trough was full and I'm just wondering if that seems like overkill or about right or what?
Before with my hands/arms, I would just grab a big scoop and full the bucket up but maybe the 8 pitch fork scoops were more because with my arms it didnt fill the trough up completely but it was maybe half to 3/4 fill. Will post a pic of my horse. Also to mention, looking at my friends horse, he has a nice round belley and rounder than mine underneath and looking at another friends horse, those were rounder than mines underneath, but from the side view of my horse, his belly is nice and round. When I feel his stomach, I have to press to feel the ribs. If I just touch the stomach, I can't really feel the ribs so I'm thinking what I was feeding was sufficient.
