Today while doing some maintenance on our run some (or just one) of our chickens ate 4 steel 3/4" screws!!! I guess chickens really will eat anything. I actually saw my BO eat one. She kept picking it up and dropping it as i was scrambling over to her but i think she knew I was coming for her precious "silver shiny bug" because down it went. I don't know if she ate all four or if the others joined her. I didn't feel anything in her crop. Any idea if this is going to be a problem?
