Not sure how far you intend on moving the coop. Is it just a few feet or on the opposite side of the property? I know when I was a kid I had a neighbor who, when it was time to move the pullets to the hen house, she would move the pullet house 10 or 15 feet per day until it was right beside the hen house. As it got closer a few of the pullets ventured into the hen house and stayed. Then she closed the pullet house so the pullets couldn't go in and the remaining ones used the hen house. So, I guess if you move it not all at once you'll be fine. Another alternative is to catch her, move the coop to the new spot, and lock her into it for a day or two. She recognize it as home and will return. Best of luck to you!
