Full estrus in middle TN. Watched 5 older bucks tending does past few days.
Another thing that is really strange this year... the 1.5y/o's are just running themselves ragged. Can't tell how many I've seen wandering around panting with mouth agape and tongue hanging out. Normally, our 1.5yo's run the heck out of the does in October, then settle down and don't participate in the rut activities, just feed and watch the older bucks having all the fun... This year, they are burning themselves out, which they may never recover from.
The only thing that is different on my places is we have a 90% fawn recruitment rate, whereas for the past decade we only had a 10-20% fawn recruitment rate. I don't know why that would change the behaviour of the 1.5 y/o's, but buck age structure hasn't changed.
