I have heard that I should add the new chicken at night so that they roost together and kind of wake up thinking that the new chicken is not so new-- sort of an "I woke up with an elephant in my bed" sort of tactic? Any truth to this? Any tips for adding a third to an existing duo of city chickens? I have two Americaunas who lay the blue-green eggs-- they are probably a couple of years old at this point. We had originally started out with three-- but it was just too much for us newbies. Now, we are determining that really, three eggs a day would be just right. Any tips?
