Hunting from the stands will work. The hay field will work too. If you are going to hunt the hay field or any other large opening, a common error is setting up in the cover on the edge. Get right in the middle of the clearing and lie down. Keep your movement on stand as little as possible and stay prone. This way they will come to the edge of the cover and should give you basically a 360 view and an oportunity for a shot. If you call from cover to an opening, they will wind you and leave before you even know they are there.
Winter time in the snow, calling from the center of a frozen pond, lake or river works well too. get prone with white camo.
This time of year the young are starting to move around. they are really naive and will respond to a squeaky screen door. :grin: :grin:
I usually wait until the cold weather and good fur, but if you want to hunt this time of year, get a howler to go with a distress call. The howlers will locate for you, but will also call them in this time of year or Feb/March. Now because of the pups they will try to chase an intruder off and F/M because they are defending territory and mating.
There are a lot of howlers on the market that are difficult to blow or just junk. I use a custom made cowhorn howler and it is user friendly and always works. For a distress call, it's really hard to beat a Sceery AP6. Easy to blow and very versatile, even for a beginner. Try www.allpredatorcalls.com
they have a wide range and a good outfit to deal with.
I usually start with a couple of howls ,wait a few minutes while I glass, then go to a distress call. A few minutes on, then glass for a few, and repeat. About 20 min. by my watch on a stand is all I do. Some guys do more, it varies on the situation.
I've never hunted PA. but this info is kinda generic. It may need to be modified or tweaked some to suit your situation.
This time of year, it is common to have multiples come to a call. A common error is kill one and whoop and holler and high five as the others run off. OR empty the firearm at the ones fleeing. It's lots of fun, but I like to kill them all. SOoooo, I very seldom shoot a moving coyote. Let them come in to the call then stop them at the range you want to shoot. I always call prone, so I stop them by lifting one leg, or saying HEY! they see the movement or here a strange sound and turn broadside. BANG! FLOP! then I yelp like a kicked dog as the others run off. They usually stop before they disappear. If you are kewl and on them , you can kill them as soon as they stop.
When you have more than one come in, shoot the furthest one first. As the others run out the way they came in, you are yelping and the shot dog is flopping on the ground. they'll stop to see what happened to their buddy. The worst case scenario is they run off and you don't shoot. That only means nothing bad happened to them, except a noise and you can call them in another day.
I think I'll stop now :grin: I hope this helps. Anything else, just holler.
