My chickens just moved into their new coop about 5 days ago and I noticed one tried to eat a nail/staple yesterday and I'm worried one may have eatin one already. I used a magnet but I guess I didn't get them all. Can someone please help me and tell me what signs to look for if any of them did swallow one. Here is a picture of what it looks like. Is it possible they could digest this? I'm so scared something could happen. I love them so much.
