My wounded chicken that is recuperating in the house managed to get a covered elastic band that is used to hold hair in pony tails. Not the thin type but the thicker kind. I managed to get her on the road to recovery...now is she going to die from a bound up intestinal tract? what should I do? If she were a cat or a dog and they swallowed string or rope, I'd douse them good with mineral oil. Is this something that I should try with her? Can birds handle mineral oil? corn oil? This craw and gizzard bit of the digestive system are new to me.
