It doesn't have to be the meat it can just be the smell of the chickens. We do this for deer when the coon dogs go off on them or other animals that we don't want them to track. But make sure you never want the dog to go after that animal ever again. Not an issue in your case but can be if it's a hunting dog like a rabbit or coon dog you should only need some feathers or a rag that smells like the chicken. Ask your neighbor to place a hand ful of rags in his chicken coop to get the smell and place a freshly scented rag around his neck or colar each day for a week or two. you may even be able to use some of the nesting material in a large ziploc just through the rag in with it. It really shouldn't be a problem getting the smell it's not the amount that works so well its the length of time. should work with same results as the rotting carcas just a little more sanitary. Bandannas work well. hope this helps.
We as humans do the majority of our sensing and iformation gathering from our eye sight and our hearing. while about 80 percent or higher of a dogs information gathering is done through scent. So just think about it it's like smelling seeing and thinking chicken 24 7 when you eat you smell chicken when your trying to find your favorite spot to pee you smell chicken when your trying to relax and sleep you smell chicken it's actually pretty cruel which is why it works so well you give them so much chicken they literally may start to gag with nausea. But it works! You could compare it to how long would you want to go or stay somewhere where there was an open sceptic would you want to eat your lunch around the hole how bout all your meals and sleep next to it. Just trying to give you a visual of how it works. We do it with our dogs that run dear by taking a piece of hide the musky part on the buck and putting it in a bag with a bandana as described. other options are musck scents for other species like fox and skunk but I don't think they make a chicken one so as I said a ziploc with some nesting material and some shed feathers should work well. Best Wishes! Let us know how you make out.
