Currently in SE SD visiting family.  I have taken a drive on the gravel roads the past two mornings.  I'm seeing some pairs  ....rooster and hen together.  I would say in about a month there will be broods showing up.  I would have to say that nesting conditions right where I am are ideal....still a bit cool...but everything is green and looking good here in Turner County.  Most of the corn is planted and some is already up!
