We were putting gutters up on the pole barn when one of our girls zipped in and swollowed a 3/8" self piercing metal screw. Couldn't get her to spit it up. Two days later and she is clearly not happy. I checked her vent last night. She had an egg in there and I can feel the screw. But there is a membrane of some sort between where I can feel it and the screw. She has been staying mostly in the nestimg box and is pretty docile. Not sure what to do but pray and wait.
