We had a hard time removing the metal clip as well. Ours came from a feed store where they mark the Pullets. We watched a youtube video on how to remove it and she does it so quickly, but ours seemed to be deeper into the wing and stuck. We got some antibiotic gel and got the area wet and tried to move it around- the chicks did not appreciate it, but we had to remove them as we read it could harm their wings if left on. (Not sure if that was true, but we wanted them out anyway) We used the tips from youtube on how to open the clip then we gradually worked it out. It took longer than we thought. I held the chick and my husband worked the clip out. It looked like it did hurt them a bit, but once they were out they were fine and never complained when we touched their wings. One had a little skin around the clip when we removed it and one had some feathers stuck to it, but we were glad when it was all over and I am pretty sure the chicks were too! Just be patient and have some gel or cream because it was far more painful to attempt when the area was completely dry. Good Luck....
