for a very long time. it went on forever!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! she seemed very aggitated, pacing back and forth, couldn't touch her, so i broke out the nesting boxes with the fake eggs inside. all the other birds were just quietly staring from their perches and this EE wouldn not come down. i did not find an egg and i had to take her ogg the perch and she stopped. what the heck? isn't it a bit early? is she going to lay soon? or did she drop an egg before i even got out there and everyone ate it and quickly climbed back to their perches and she was ticked?
