No, he's not as big as you think. Part of it is the way he's standing. He's perked up.
It does have nice points, not much mass. As well as I can tell it's a 7-point, I'll guess him at 14, maybe 15 inches wide?
I had a small 6 or 8 point on this camera until February or March? More than likely, he's one of the 2 in this picture? Just my guess, I'd say if they make it till December, that would put them at 2.5 years old.
We had a really good acorn crop last fall, and not much winter. Look at his hams and shoulders, our deer should have wintered over very good. Who knows?, maybe that mineral salt block is helping their antlers? It can't hurt.
