My sister informed me that she thinks my 25 week old buff orp "Ethel" gobbled down a staple while the girls were free ranging today. I looked in Ethel's mouth (I was shocked at how far down I could see) and didn't see anything and I got out the old cow magnets but they are bigger than Ethel's head and proved useless. What do I need to do or watch for? Any way I can increase the chances of her passing it safely? Thanks for any info. She's our friendliest chicken, I'm very worried about her.
