We're building a new shed in our backyard and there were some screws left over from our old one that we tore down, and i guess we missed a couple because i was watching my one chicken playing with something, and it kinda looked like one of the 1/4 inch metal screws from the old shed. before i could get it away from her she ate it and im freaking out!!! she seems fine so far but i dont know if i should call the vet or what? i dont want it to hurt her and shes our pet, id never forgive myself if she died because i wasnt paying close enough attention to what she was doing! please help! i dont know what to do!
