no. Where are you located? You guys need to give us more info if you want good advice. are you sure they are pine trees? if you surround the field with pines you will limit the sunlight. Plant the pines thickly at the north and west end of the field. This will act as a wind break and give the deer some bedding/cover in the winter. Once you move these trees, you run the risk of them dying unless you care for them.

Are they white pines? (5 needles per stem clump) red pine has 3.
