The duck is surrounded by hostas, impatiens and potting mix. The nest is protected by yellow tape, a sign that tells customers "Please do not disturb the duck." Home Depot's Brenda Hatch, who works in the lawn and garden section, she feeds and waters the duck every day.
The duck showed up last year too, and employees put her in a box and relocated her and her eggs. But she returned about three weeks ago.
The Bangor Daily News says the duck flies off every day, but returns within an hour.
Experts say the eggs should be about ready to hatch.
