One of my girls, Millie, just recently started laying. Right from the bat, she started stealing any real or fake eggs for "her" nest box. We are home during the day and check the boxes often, and she gets mad when you take the eggs away. If you take the egg she's laying on, she looks around for another and will go lay on any egg she finds. We took away the fake eggs, check for eggs every hour or two, but she keeps at it. She'll growl and huff and puff, and wander down to the run after a bit. Is it normal to have a Barred Rock act like that right off the bat? Is there anything else I can do to discourage her? I wouldn't mind, but we have no roo and don't need more chicks.
