based on the weather patterns I have seen this week on the models I would say that this current front will cause some bird movement. IMO it will push the birds up north further south and at the same time push the birds from the middle area further south, yet wont effect the birds that are already south at all. Now when all this takes place you will go from having no birds to a few more birds to more birds and then back to no birds, so you are going to have to keep a careful watch on your fields and know when to hit em.
now for the real kicker that will make all the difference in the world...if you can figure out where you are in the big scheme of things you'll be money. you need to figure out if you are north, middle or south, once you get that locked in you can formulate a plan and get the job done
