Chook Me!

How take the subject of a photo and place it onto a different background on photoshop elements 8? So......I want to submit a picture of my beautiful brown leghorn rooster to the Backyard Poultry magazine. I was able to snap several very nice poses of him, but the background image is not the prettiest. How do I take the roosters body and put it on a different background such as a snowy scene using PHOTO SHOP ELEMENTS 8? Thanks a lot!
