Hi, I just got some of these to put on one of my bantam hens. She has been pulling tail feathers and finally caused an injury to one of the other hens. Anyway, the prongs that go into the nostrils seem really big and I thought I would ask if anyone here has used them on bantams. I could only find one size--no one seems to make a small size. Before I start messing with these, was wondering if anyone has some tips. I have Bantam Faverolles. Thanks all!
