My 2wk old keet swallowed a string from a feed back. I couldn't pull it out so I cut the string off at the mouth. Don't know how much is inside. Will he die? Is crop surgery advised?
My mom brought home two chicks that had been hatched in her preschool (she is a preschool teacher). The first day home, I was watching them and happened to be facing the back-end of one. She started pooping, but instead of being a quick poop, like usual, it kept going. It ended up being a rubber band! Yuck! I'm glad I was right there, because the second it was out, the two of them started fighting over it. Not surprising, rubber bands look just like worms. I was able to snatch it from them. I have no idea how many cycles through it made.
In my experience, I have found baby chicks are quite resilient. While you want to keep them as healthy and happy as possible, sometimes they find a way to get into things they shouldn't. But often they will find a way to work it out.
