Today one of my hens found a 10cm piece of silicone out of a caulking gun nozzle and decided to down it whole. What transpired was a rushed visit to the vet and emergency surgery to remove the silicone from the crop. We were able to take her home pretty much straight away. I have just reintroduced her to the run with her sister after being kept in a quiet warm place for 2-3 hours. I figured with the racket that she was making calling for her sister that it would be less stressful for her for them to be together. My other chook, the dominant one is free ranging and being kept away from the 2 girls. She is alert, eating drinking and acting like nothing has happened. I have put ACV in the water and i have just started her on the antibiotics that the vet gave her. Is there anything else i should be doing?
