Lol, I find this to be true. Mine has been too occupied with how he can get to the other side of the separation fence. To me, mine seems like he is eating and not getting skinny but i do notice that 2 cups of feed can last almost 3 days. He will chow down some food but only when i am in the pen with him or when i decide that his mate can partake in date night! It's almost like he doesn't want to eat alone or might miss out on something while he eats!
