I don't know how you throw your hay, but with my two I found that if I just put 3 or 4 flakes out for each of them in two piles that a lot of it was getting wasted. I've started spreading out the flakes into different places. This morning there were 8 flakes all together in 8 different spots...where they had to walk to each flake. There is basically no waste anymore, even with them getting that much twice a day. With this type of feeding, both of them are starting to gain weight. I'd rather mine to be a little on the chunky side going into winter...instead of trying to put weight on them once the bad cold weather actually starts.
I would also contact the investigator. It may help you out in the long run. He/she will probably tell you if you need to start looking for another barn.
