Yea health of the deer has as much to do with it as age. A healthy doe fawn will generally be bred as soon as she reaches 7 months old, assuming she is healthy. In Wisconsin, the does don't always hit the 7 month milestone until after the rut hits in mid-November, but they will go in estrus during December or even January and will most likely be bred as long as she is healthy. I'm not familiar with when fawns are generally born or when the rut is in Texas, but if she's big and healthy and old enough, assuming the buck:doe ratio isn't too out of whack, I'd say she'll probably get bred this year yet. On a side note, bucks can successfully breed at 5 months, as long as they are healthy and somehow find a receptive doe that isn't being trailed by half a dozen racked bucks.
