A majority of the hens will nest around the same time each year. Usually when you start seeing lone hens they are nesting or looking for nesting sites. I haven't seen any yet. The weather doesn't have that much to do with nesting time. The season should be just fine. Lengthened days has more to do with nesting. The gobblers didn't gobble much past couple mornings. Even though its been pretty nice. But still got pics of a lot of birds on the properties I hunt.the season looks like its gonna be good. Goodluck this season.
