I just gave my chickens some apple. All were eating just fine. I decided to pick up one and check her vent b/c she's had some runny poo lately and a turned her upside down to do so. Her vent was okay, but when I put her down, she began to sneeze, cough and now is making a gurgling sound!!! I'm so scared. Please help! She seems to be doing okay now. That was so scary! Tomorrow I'm going to take a fecal sample to the vet to be checked b/c she's been having some really runny poo...almost all watery with some yellowish color. If anyone's interested, I'll post an update tomorrow after the vet checks the fecal sample.
