Not sure where to post this so I will post it here. I have 15 month old female Austrolorp and today I noticed a sack hanging out of the rear that is about 2.5 inches long. She is up and moving around. I not sure if this is where the egg is delivered or the waste. I am assuming this happened while laying the egg. Is there anything I should be doing. I am keeping her away from the other chickens because they keep pecking at the sack. Thanks for any help.
