Oh yes! They can do a snatch and run...faster than you can react, sometimes.
I had a hen rip my CZ stud right off my earlobe just a month ago. She was walking on the rear of the coop, where the nest boxes protrude. I was bending down while cleaning up. And wham-mo! She snatched my stud...
Well, after two weeks, it most likely has passed. I doubt it is still in her crop. If her poops are normal, the crop has been emptying daily. If it was stuck in the gizzard, she would be showing signs of digestive problems.
So, enjoy your hens...maybe dice the bologna before you take it...
