I have now appointed my DH as resident Ch. E. (chicken engineer) He is a Navy retiree also trained as an EMT. For some reason our oldest hen and dependable yearly broody decided to eat a piece of rope she found in the yard. I found her sitting in the dog house with about 12 inches of 1/4" rope hanging from her beak, the other 10-12 inches down her gullet. I couldn't pull it out. So I carried her up onto the porch where my resident Ch. E. was sitting and showed him what had happened. He immediately went for a dropper and a bottle of canola oil. After putting about 6 cc of canola down her gullet and tipping her head back, we were able to pull the rope out. It had a big knot on the end, which had probably been in her crop. (My Ch.E. called this a reverse intubation) Said chicken was last observed eating scratch in the run and drinking water. I think she'll make it, due to the Ch. E's EMT training. One should always have a resident EMT when raising chickens.
