Help! This afternoon I went out to hang out with my chickens and noticed one of our welsummer hens had this huge blob hanging off her bottom. I washed her off with warm water and a paper towel (as best I could, she's a lively one) but the blob remains. After taking a closer look, it seems like she's got an egg stuck in this membraney sac that's hanging down. I can't find a way to help push the egg out but maybe I'm not looking in the right place. Will she lay this like any other egg or is there something I should be doing to help her along? She doesn't seem overly distressed, she's just walking a little funny.
