No - not double cropping, just working hard!     That more than likely is a pretty mature doe.   First of all she has the ability to actually support 3.    Then she has the experience to keep all 3 of them alive to this point....    Now.....she is probably the one you will hear blowing at you come October as well.....so that experience can be a double-edged sword.   In any case, it's always nice to see habitat work.....actually working.
