I was doing some baking and watching my hens out of the window when I saw two of them squabbling over something on the ground. It was something white, flimsy and a couple of inches across - it looked like a corner torn off some kind of packaging, and must have blown there over the fence from the street. Before I could get out there to take it from them, one of the hens had swallowed it! IDK if it was paper, foil or plastic (I'm hoping paper as presumably this would be the least harmful!) But is this a vet job or is it likely to pass through? I'm not even sure which hen it was, as they all look very similar unless you're up close!
