so my chicken doesn't eat worms or slugs or beetles but he eats nails. i guess i dropped it when i was making the coop but he ate it. ive seen him try to eat them before but i always took it away before he did. whats gonna happen to him? he seemed fine right after he ate it and 2 hours afterward, now hes asleep. the nail was 4 centimeters long. im worried, i dont know how it can go through his digestive system without puncturing something, what should i do?
