If your talking up in the Fort Collins area there are a lot of birds. They are flying in medium to large groups and are tough to decoy. You can kill 'em though. Go with a large spread and a lot of calling on the lessers.(which is most of what you will see) You can back off the calling if you get some of the bigger birds, but they still need to be called. Depending on where you will be hunting, there could be a lot of competition.You should have some weather on Friday that should help you out. You might even get some fresh birds moving in. I would put out every decoy you got and try to look as big as you can. Good luck.
