I think it varies greatly by area where we are at... Generally I would say our birds are still henned-up and breeding with a few older hens probably already sitting. I think the late green-up this spring (dry weather) contributed to the "late" start. I'm thinking that in a week or less it should bust loose again. Just be there when it does!
As far as tactics and the ones you listed... Yes, try those!
Seriously, they've all been known to work. Late morning can be good right now as well...
