The little one in the back looks like a "lunger". He only ran about 200 yards while I was taking pics and he is sucked up behind the ribs and had his mouth open the whole time. Look at the hip on the bigger buck.....fair amount of bone showing. Like I said, I think the bigger one will make it, the yotes will get the smaller one.
But no, I don't know why these two look poor. The good news is that they all don't look this way.
