I think that the deer in that top trail cam picture is 3.5. When its spring, and the hides are thin, and the coats are that bright brown..it can be difficult to tell for sure. Most of the deer we see and determine age on are in winter regalia. But I'm going with 3.5 this coming fall...maybe 4.5. But he is definately not 2.5 and definately not 5.5.
