...July seems a bit hard to understand the fawn would show up in Mid winter...
...maybe you opened one that was real Ugly and just Took it for the fact that she couldn't when all the rest did...
What "Winter"
I've been here all of my life. It doesn't get COLD here, not really. Cold, what's that?
I remember as a boy bundling up in the mornings. By mid-day the bundling was all off and it was back to short sleeves. The "cold" here is nothing for our fur coat wearing deer except a chance to kick up their heels and move around. BTW, the Atlantic Ocean, Banana River, Mosquito Lagoon, Indian River, and St. Johns River are all within 20 miles of one another with my place in the western 1/3. I suspect the "heat sink" of water has a stabilizing effect on the weather keeping it warmer perhaps.
The doe killed last year was not the first one with fetuses and not the first showing late Summer gestation dates. Apparently the deer east of the St. Johns River in East Central Florida are getting it done earlier, and perhaps all the time, but certainly more "testing" has yet to be performed.
