Consistently tame weather certainly can't hurt anything as far as turkey reproduction success goes. It seems that a mild winter has helped the insect population, which should also help the turkeys by increasing the amount of protein available to them. As long as we don't get those tropical weather systems to spawn hurricanes, it should be a good year for them.
I talked to a buddy who said his hay mowing destroyed a couple of turkey nests last week. It is probably late enough that those hens won't re nest. Plenty of other nests had to have survived on his property though.
Luck Counts, good or bad
